Wrong Version number in the backend (3.6.2)??

Hi

On my website the community survey component told me that there is a new version (I had version 3.5.9 and the new one is 3.6.3).

I downloaded it and installed it. Now the backend tells me that I have the installed version 3.6.2 instead of 3.6.3. When I go to the extension manager it says that I am usin version 3.6.3. What is now correct?

Best regards
Andy
