ZJ Beny EV charger review

Hi all. Finally got the latest solar DLB unit installed. Everything is working fine except when I start charging in PV mode it comes up with Max Current as only 6amps? I thought this was supposed to increase and decrease with your solar output? Have contacted both the distributer and customer service at head office, but no solutions so far. Does anyone else have this issue? And I have set the Max amps to 32 in the app.
