Group borders overlapping - how can I solve this?

Hello,

I would highly appreciate it if someone could help me resolve the overlapping of borders I am experiencing (in the Repeating group).

The borders are only from the group which is in RG - so RG does not have a separate. I need to solve it because I need to change the color on hover.

I’ve tried searching over bubble forum but I couldn’t find a solution.

Best regards,
T
