Help with printing after update

Hello!

Recently I decided to update the firmware of my Artillery Genius Pro, and, after it was done, I did a manual calibration and got to testing it. But I'm having problems with the first layer. I want to know if there is a known diagnosis for this patterns (the ones that look like an L are on purpose). I'm using adhesive glue so I think this is a problem with the levelling or the Z-axis, but I'll appreciate some advice. Thanks!
