Problems with Pytes V5a - max charging current = 5A/V5a at 65% SOC

Good Morning
The last few days i let the BMS manage
The day bevor yeasterday it had a effect during discharging: in 12 minutes, the SOC dropped by 32%.
The current was averaging around 43A, for 12 minutes → 9Ah → 9% SOC, and not 32%.


Then in eavening the SOC was “frozen” at 20%, even though at least 3A was drawn over about 5 hours.
Shouldn’t it have dropped by about 15%?
In in my opinion BMS “forgot” correct soc.

Yesterday again in charging phase Unfortunately, the problem persists: Yesterday, at 52% SoC, the charging current was limited to 5A.
And that was over a period of 4 hours!!
Accordingly, a lot of power was being drained into the grid.

I am not satisfied with this behavior, I have written to my dealer in the hope of getting a solution with Pytes Battery
Maybe there is also a software update for the BMS
