Why did my available app update disappear from the app store

Question

A few weeks ago, I had an update available for one of my iphone apps that I chose not to download since it was said to have bugs.  As a result, I had an outstanding badge app icon.  Just today I realized that the alert was missing.  At first I thought I might have accidentally updated the app when I synced my phone last, but when I search for the app in the app store, it still gives me the option to update (I've included a screen shot below). It just no longer shows an available update under the update tab (see second screen shot)  It's not a huge deal at the moment since I don't want to install this update, but I'm afraid the problem might continue with future updates I want to install. Any ideas? I restored my phone from an icloud backup a few days ago, but once the restore was complete, the update alert still showed correctly, so I don't think that's the problem.

It's good to know I'm not the only one with this problem.  I had noticed the issue with my downloaded apps displaying the price, but I thought maybe it's always been that way since I never install apps through iTunes on my computer, just my phone.  My husband's computer is doing the same thing, but he didn't have any outstanding updates on his phone, so I'm not sure whether his phone is having the same issue.  My guess is that if other people are having this problem, they don't have any outstanding updates, so they aren't aware of it.  I know many people who make a habit of not updating apps have jailbroken devices and can install an app that hides the badge app icon.  I guess for now we need to wait it out and see if the problem fixes itself.  It's still annoying though.
P.S.- I just noticed that on my phone if I search for a previously installed app, it just shows the price instead of giving me the option to "Install".  I can reinstall it by brining it up in the list of purchased apps, so it's just when searching for the app.  Also if I search for a currently installed app, it says "open" instead of showing the price, so it's only with previously intalled apps.  Whatever the issue, I hope it's fixed soon.
