Sometimes the autoranging fails and instead of changing the range, the displayed value is just wrong.
Very dangerous...

Nobody else has ever experienced anything like that. There could be a fault with your meter. Did you capture it on video?

the lack of backlight and auto power off are really strange. what´s that cost, 1$? personally i don´t miss a backlight too much. but i´ve had my batterie drained a couple of times cause i left the damn thing on for 2 days straight :) good thing i got recharchable 9vs
btw, there´s an easy tutorial on yt on how to add backlight

If I remember correctly it appears the * means alternate locations. I don't know if they are there to allow them to source cheaper parts or what but often they are not populated.

I would guess that they are values that are subject to change or adjustment for trimming accuracy. Here is the schematic.
