Iphone will upload apps but cannot transfer purchases to itunes

Question

On my Iphone a number of apps were deleted.   I think this was due to me syncing with itunes. In itunes you can see the list of deleted apps by name (no icon).  The app title has a selectable status of ‘remove’ or ‘will remove’.
I reinstalled the deleted apps to my iphone from within my iphone by going to the Apps Store and using ‘Purchased’ apps from within ‘updates’.  So the apps are back on my iphone.
Within itunes/file/devices I used ‘Transfer Purchases’ from iphone, however the apps have not been restored to the iTunes apps list. (There was no pop up window advising of any issue). The app associated ‘Remove’ / ‘will remove’ status is still present suggesting that that is exactly what will happen on the next sync.
From within ‘itunes/store/check for available downloads’ I am advised that “all purchases have been downloaded for this apple id”
The issue I believe is that I changed my apple id as the one I used was an old email address.  I swapped ISP and hence have no access to the original email / original apple id.  I cannot re-enter the old email id as an alternative to my current apple account id as I cannot access the email in order to provide the necessary verification.
I am not sure why from the iphone itself I am able to access all previous app purchases irrespective of the apple id (or are these coming from backups in the cloud?), but in itunes this function does not seem to be available.
What is the solution? Could apple help with this if I call them?
Appreciate your help.

If the apps are showing on the phone's Apps tab on your computer's iTunes then that implies that they are already in your iTunes library. You've checked your library to see if they are there ?
The 'remove' button means that the app is installed on your phone, you would click on that 'remove' button if you want to remove the app from your phone - that will change the button to 'will remove' and clicking the sync/apply button at the bottom right of that screen will then remove it from your phone. Not clicking on 'remove' will leave the app on your phone. (Similarly apps that aren't currently on your phone but only in your iTunes library will have 'install' against them ; clicking on that would change the button to 'will install'.)
You can redownload items on your computer's iTunes (as long as they remain in the store and you don't change countries) by clicking on your name towards the top right of the iTunes screen and selecting Purchased from the popup e.g.
That will take you to a screen where you can potentially redownload that account's past purchases (if the item is already in your iTunes library then it won't show for redownloading).
