Advanced Tech-Tree issue: clicking on "View in Garage" shows tank needs to be purchased and I own it.

For example I own the premium Chi-Nu Kai. It correctly shows the "check" mark.  

If I click on it the tank the equipment view is shown.
When I click on the "View in Garage" button it displays the Gold cost and the "To Purchase" button but I already own it.

I also noticed this shows up when clicking on any already owned tank.

I see, however I cannot anything about it.
