ZJBeny only "charge now" at 5A

I’m having a strange problem that only came to my attention now that I had to charge a bit faster overnight.
On solar tracking, my system works beautiful and feeds the car exactly according to my solar intake up to the top limit.
On the other hand, using the charge now option, I can’t get more than 5A. I’ve changed every option I could find that set my minimum charge to more than 6A, but noting worked. Any ideas?

@marsreis if you let us know a date and time when this happened we can have a look
