Weird pattern change issue

Hi all, when I am in the default ‘sequential’ pattern change mode, it is not working properly with some of my patterns. When I do a pattern change, it will move forward 2 steps, and then directly jump to the beginning of the selected pattern. When I copy and paste a pattern into a new slot, it does the same thing. The other 2 pattern change settings seem to work fine.

This only started with some patterns I made earlier in the week. Older patterns do not have this issue. Has anyone had a similar problem? Thanks!
