I just had this problem myself, and was about to post nearly the exact same picture last week. Try unplugging the charger, closing the charge port, then access the tools > Charging > Current screen. Mine was set to a max of 55A there, which only allowed me to go up to 55A from the plug icon when charging. It also limited all ACC commands to 55A max.
I only wanted to test to see if my HPWC could supply 70A. Now it's back down to 40A max, since that seems to be the sweet spot for charging. I've never needed to charge faster than that.
