[Clerythecleric]

Hello,

 

Can someone tell me please how to remove this like background part of the tab? I added a snippet from another post so that i can color the tab backgrounds but now I have this? Before it had a white background which i could hide but since changing the style its like the tabs  aer being cut off at the bottom. Any help appreciated thank you.

It would be nice if you could update your post with a working example, it's missing includes and I have no idea what the $test variables should be set to and/or if they are related to the issue you are trying to solve.
