Apps' content in Chinese despite correct region set

Question

Hi Guys!
Let me start off by saying this is my first post and I've just set up an account with sole intention to seek advice. I really hardly ever register onto online boards where I have not contributed previously and start up threads that junk it up. I believe it's rude and that people should google extensively prior to starting posts asking for help. I did, however, google, and a lot, and I have not found possible cause of my problem/way to solve it and not even a single case like it O_o.
So I think asking others might be my only chance. Especially since I know VERY LITTLE about Apple products and I've had an Iphone for like a month. So maybe there's just something really simple I'm missing.
Here's the thing:
iphone 4s, iOS 7 (have not upgraded to 8 and would rather not for now)
problem : free apps from App Store I download, have widgets in Chinese! >_< . The store displays them as it should, in English. The apps descriptions are normal too. The Chinese only shows AFTER downloading and running them. Store region is set to Poland (that's where I live), prices are displayed in Euros -as they're ment to be, some apps display properly after buying but others do not (example: Puffin browser, Amazon app, Documents 5 pdf reader)
I tried removing and downloading these apps again, shutting my phone on and off, logging in and out off App Store, double-chacked there's no Asian country set anywhere as locale, to no avail - problem remains >_<;
This issue started at a very particular moment:
when I started messing with the regions option
By "messing", I just mean that I had to 'pretend' to be a US  citizen(temporarily changing address and phone details)  to access US App Store instead of my default, Polish one. I needed an HSBC bank app and it was not released for Polish Store (ridiculous!), so I changed to US Store, downloaded the app and changed back to my regional store. HSBC does not display in my "purchased" apps list, as if it's not recognizable ( since bought/downloaded from different store level), but the app widget is still there and it works just fine. (no Chinese lettering in the app itself, just it settings).
Since then, I'm having this language problem on random apps I obtain. Have I messed something up by changing to US store that one time? Or is Apple just punishing me for tricking them in order to download that HSBC from a foreign country's AppStore?
Either way, it's so troublesome! I need acess to these apps, but I can't read a word they say >_<
They're useless and there's no way to change language settings for them anywhere.
Do I go back with my phone to the store and cry or just try setting up a new AppleID and logging on from it? (I really would rather stick with current one )
I'm also thinking about getting rid of that HSBC app from the US Store, since it seems to be the cause of the glitch, but it is my bank and I kinda need it >_< Would be sweet if I could keep the "smuggled in" app and fix that bug.
ps. Amazon app actually displays English content, but welcoming screen is for Amazon.cn (China) and some options are in Chinese as well >_<
Any help or advice would be greatly appreciated.
Thank you for reading.

It sounds like you will have to contact the App developer.
You can find the developers contact information on the application information page in the App Store.
