Image occlusion cards / clozes are only showing up at end of queue

Image occlusion cards within a card set are showing up at the end of the queue instead of in-between the other cards. The same issue happens with clozes. I have tried out numerous settings, but nothing seamed to work. Does anyone have the same issue and/or knows how to fix it? I am using Remnote for m1 mac, default remnote queuing system, pro version.
