I have this problem too!
I found a fix for that. It seems that suddenly, the Store app remembers some inexistent updates (?).
To fix that, you have to go to the %temp% folder (WIN KEY + R, enter %temp%) and you'll find a file called winstore.log.
You have to delete this file, but you have to close 2 process first: Runtime Broker and Com Surrogate.
Runtime Broker it's easy to close, but Com Surrogate restarts automatically, so you have to close again, and delete winstore.log inmediatly.
Once you have deleted it, restart your PC. When it restarts, maybe you will se the "2" number (in the Store tile)... Open it, and you'll see the "2 Updates available" is gone.
