I had exactly this same problem, with arrow on the top, after using the DC mode. I have not used DC mode since then, however. I'll try again to see if I can reproduce it again.Thanks for your answer.
As you can see in my picture, in battery mode the „back“ symbol is on the top which causes the problem I think.
Very suspicious
Firmware 1668044570 : I'm not sure if it is the last one.
