App Store shows updates, opens apps instead, update through search
So I have the badge showing 8 updates. The update tab shows 8 as well. I clicked update and it opened the app instead of updating. I used the search tab and searched for one of the apps needing an update. Here the app shows open. I clicked open and it prompted me for my apple password (shouldn't happen for updates btw) and then updates the app. I go back to the updates tab and it's moved down under updated October 10, 2014 but still shows update. I click update and it opens the app. I went back to the search again and clicked open where it opened the app.
