Reversal Rotary issues

I have an atomstack a10 with a atomstack r3 roller. I was able to set it up with no issues, went to burn a single letter to a glass, and it came out reversed. Went into rotary settings and chose “mirror image to rotary” and the next one came out fine. I then added more letters (a name) to the same project, and it reversed it again. the mirror image to rotary was still checked. What am I doing wrong here?
