Figma slots not properly mirroring on App

Hi guys, as you can see from the ss, the custom figma slot, doesn’t get properly mirrored on Figma app. As soon as I “double click” somewhere on the designed components (randomly), the components get auto-adjusted on Figma app too magically. 

I think it’s more a rendering bug, but I might be wrong.

Anyone experiencing this behaviour? 

Thanks
