I am currently using OJS 126.96.36.199
I catch an error when ordering categories. After ordering categories, then edit a category, the list will be sorted in the wrong order - that category will move to bottom.
Thanks for pointing this out. I tested this in 3.3.0-8 and can verify that it is also the case.
I’ve filed a bug report here: https://github.com/pkp/pkp-lib/issues/7697 so our development team can have a look.
Thanks for your attention and the bug.
