New stamps erasing/destroying old stamps

When I place a stamp near another stamp the older stamp will have a portion of it disappear. It can be anywhere from a small portion to almost 90% of the older stamp disappearing from some invisible border. The only way if found to fix the issue is to erase the stamp and refresh my page, however the clipping issue still happens even if I completely back out of the map and reopen inkarnate in a new tab. I've tried looking up solutions but I can't find anything.
