I have my model mirrored, that is why I can draw from both sides but I’m just confused about how on 1 side I can draw twice? Is there a fix for it or a tutorial I could follow to fix my error?
Sorry if I’m not explaining it very well, English is not my first language 
Is it painting through the model? Are you painting on the backside on the other side of the mirror plane?
hihi! thanks for your response 
Turns out what I didn’t do was apply my transforms with ctrl+a and it fixed everything, I never knew even that the brush settings had a symmetry option so thank you a lot!
