Overbuilding treasure maps

[Grintus_real]

Hello,

I just wanted to ask if I probably do something wrong.
If I build a cat above a same colored treasure map, I may take a common treasure?! At least I read this in the rulebook.
But as BGA told me to pick one.. I can click everywhere, but it does not let me choose one.

Is this a bug or am I missing something here?

Best regards,
Grintus
