Slow charging on Hub A1

I have a pair of Apex 300/B300K combinations that work perfectly by themselves. When connected to the Hub A1 and using the L1 power input on the A1, neither Apex will charge above 550 watts. No matter what switch combination and app combination I try, 550 watts seems to be the charge limit. I CAN adjust the charge rate down but anything above “Quiet” charging mode is limited to 550 watts.

If I disconnect from Hub A1, everything works as expected.

Anyone else seeing this or am I possibly missing something?

Hello,please check the firmware version of HUB A1, the newest is 908109/908703
