Status Battery Charging does not change 0A charging 55,1 V SOC 77%

I have a LIFEPO Battery pack 16 x 3,45V is my setting. This worked since February fine with no problems. BMS is Jabaida which works also fine with Cerbo GX.
Now Victron Multiplus 2 5000 keeps charging with 0 A at SOC 77% and 55,1 V. I would expect that Multiplus would switch to discharge the battery instead of taking power from the grid.
This worked in the past verry well but now once in sudden the discharging mode does not work any more. ???
