Looks like it’s indicating level in both pictures to me but it’s probably true that it’s out of calibration. Reading different after a 180 degree rotation suggests that the vial itself is slightly out of alignment with the level itself

Calibrating the level is easy though: https://armstrongsupplies.co.uk/blogs/faqs/how-to-calibrate-a-spirit-level

Yes the level is off but can be adjusted with the screws that hole the plastic on the aluminum.
