Phoenix IP43 Smart Charger 120-230V reports totally wrong DC current, and other.. bugs?!

Yet another bug:

Setting the Max Charge current so that it limits the current actively: normally my 2,65ohm load would consume 9A at 24V. When the Max Charge Current is set to 6.2 at 24V, the voltage drops to 16V and the current to 6.2 (Victron always offsets by 0,6A for some reason, see above posts). Setting the Max Charge Current higher makes the voltage revert to 24V, but this works only once! After that the charger hangs forever at 16V..

This also happens with no other Victron apparatus connected to the Charger. Connecting the Cerbo makes no difference in this behaviour.
