A shade is added to my component when copy pasting it into a variant

Hi everyone !
I’m getting my hands on figma and I love it so far.

This morning, I encountered an issue that is close to driving me crazy, altought it seems super “simple”.

I wanted to create three state of a product display (normal, hovered and “on click”).
For the “on click” state, I wanted to display a list of options below.
However, when I copy/paste my list of option below my third variant, a slight shade seems to be added to all my labels and icons.

Top is what I got when I paste my list into the variant, and below is what I wanted (normal group, not added into the variant) :

I manually checked each layer to see if any effect was added : there is none.

I’ll thankful to the person that can help me :smiley:
