Cycle Count Status not updating

Hi

Please advise what could possibly cause the status of an 'Entered' cycle count to remain at 20 and not move forward to 30?

The entered quantities are saved properly, it is just the status that is not incrementing.

One client of ours encounters this problem with only one Location within a Branch/Plant (she creates a different cycle count number per Location), out of 9 locations it is always the same one that does not move forward.

Only after clearing the cache in the server does it then work.

This is a very large organisation that counts at the same time nationally.
