Mova 1000 map

I have a MOVA 1000 for a year. After the last firmware update it does not save changes to the map. Example: area expansion, border expansion. After the change it requests approval to merge the old area with the new one, but the change does not appear on the map.
Mova 1000, Plugin version 1.8.4, firmware version 4.3.6_0450

do you have some solution for this problem?
