App Store Keeps Pushing The Same Updates

I've got the following apps installed:

Text Wrangler 4.5.12 XCode 6.1.1 Microsoft Remote Desktop 8.0.12

I've installed the updates no less than 7 times in total in an attempt to get rid of this and it's still trying to push the same versions on me.

I was hoping that the recent OS X NTP Security Update would have fixed this (I was thinking that the date issue might be the cause) but these updates have just appeared again.

What can I do to stop this ridiculous situation?
