Finance Cue

I met the weird error. Steps:
1. Open RTC to role center - Bookkeeper
2. Remain open only role center page without any interaction
3. After period of time NAV shows error: Finance Cue table design has changed. Repeat you action later.

Environment:
- NAV 2016 Build 43402
- Finance Cue table contains about 20 fields in area 50000-99999 created the same way as standard fields (only flowfields), but not changed for a months

Where to find the reason?

Thanks in advance
