Hello,
We made some improves in our latest update but we found that for your case they cause such issues you described above. We added force enqueue of styles (quick view and popup after add to cart) so now they are styled well as before. It will be working after update as well – just keep that code in your child-theme and don’t remove it.
Code -> https://prnt.sc/m3kwTfFFxkGQ
