I am having similar issues. My main component has a stroke of 1px (set by a variable) on the bottom only, but all the instances show the stroke on all sides instead. The issue seems to be related to the stroke width being set by a variable, because manually entering the stroke width in the main component caused all the instances to display correctly and for overrides to persist. Hope this works for you, ​@ClaireLee!

Thank you so much your kind help! Yeah, I doubted it but didn’t try remove the variable. I think there are couples of bugs related to variables. I hope they can be fixed as soon as possible.

Have a good day pal!

Same issue here the stroke kept showing on all sides instead of just the bottom. Fixed it with ​@Rae_Gibbs1’s tip — thank you!
