Redwood UI for creating Cycle Count has issues

Summary:

We have cycle counts defined in old UI. We use categories for item assignment. And we count serial numbers.

Client switched on the Redwood UI. But the sync is not working. When I change an item's category value and sync with the Add option and then also the two suboptions to synchronize and delete … and going to next an autosave is done. But in the Items to Count the item still shown in the old category.

Then at end of changes I press Submit and get an error mentioning serial info change but I had not changed that. Only the item itself (category assignment) and a sync.
