App Store not seeing Final Cut Pro X store purchase

App Store not see Final Cut Pro X store purchase.

Here's an odd one for you.
I purchased FCPX from the App Store and installs as it should but it shows "INSTALL" in the store and when I click on it I get a popup that says:
"Final Cut Pro 10.0 is already installed and was not purchased from the Mac App Store Do you want to buy Final Cut Pro 10.0 again?

I purchased Motion and Compressor and they both say "INSTALLED" as they should.

I have to straighten this out but there's seriously a potential serious fallibility in the App Store.

I see no related issue at the moment and have no problem with Software Update downloading Final Cut Pro X Supplemental Content, Motion Supplemental Content and ProApps QuickTime codecs
