Component resizing/scaling behaves weird

Hej guys,

I have a set of icons, they’re in a main component as variants. All variants have the exact same settings, but still resizing leads to different restults. This also effects the instances, which makes them kind of unusable in other components.

I tried literally everything I could think of or found using the search, I tried using groups, frames, auto-layout, all the different auto layout settings, adding strokes, editing the vector, and and and… nothing helps. I’m desperate. This also happens when I throw two scaling/not scaling icons into one variant – one scales fine, the other one refuses to do so 😦
