I am having this problem but on modded 1.19.2 (doesn't happen in vanilla, and afaik nothing change from when I last played and it worked just fine). Have you figured out the issue by chance?
its not a duplicate bug
it was caused by itemscroller not optifine, and wasnt a cartographer
Turns out this is an issue with the item scroller mod so just FYI to anyone out there with this problem as well
afaik it seems to be random
barthotymous
