Conflict With Advanced Custom Fields Relationship Field

I’m using and ACF custom field that’s set for the Relationship field type. That allows me to choose posts from another custom post type to display in the current custom post type. Once the posts are chosen, I can reorder them by drag and drop.

I noticed that the reordering was not working correctly in the ACF field, so after some troubleshooting, I discovered that there’s a conflict with the Post Types Order plugin. When I disabled PTO, the ACF field works and displays correctly. When I enable PTO again, the ACF field does not work correctly.

I tried unchecking the Auto Sort option, but that didn’t change anything. Any other suggestions?
