print settings what does the (U) mean

I have installed Prusa Slic3rPE. On Repetier, it is showning (U) after the names of any config for Print Settings, Printer Settings, and Extruder 1. This does not appear for Slic3r.
What is it trying to tell me??


  • PrusaSLicer comes with lots of predefined profiles that you can not change. The (U) indicates it is a setting that was created by the "User" - so these are settings modified by you.
