The usual convention for X0 ,Y0 is at the left hand corner nearest to you.
Assuming your horizontal axis is the X axis then if you go to Config. / Ports & Pins / Motor Outputs then change the Direction Low Active state for the X axis that will correct your letters being in reverse.
As for the letters being on top of one another - that could be lost steps, try reducing your Velocity and Acceleration settings by 50% (in Motor Tuning) for the X and Y axis, save the changes and report back on the result.
