These values appear in the preset edit but do not make their way to the G-Code. What I get in the G-Code is:

Specifically, I invested a lot of time developing recipes for several flex, nylon, and nylon/CF filaments. I am getting ready to undertake this effort for PVA and BVOH. This includes user defined print, filament, and printer settings which I have saved in projects and exported as .ini in an attempt to . If I open PrusaSlicer from the program icon, often they do not appear. If I open PrusaSlicer from the projects, they sometimes disappear, or the user settings appear to be lost, or the name of the user defined setting is lost (it appears as a default (modified) setting). At times, print settings from 1-2 years ago which have been absent have suddenly appeared.

All of this is extremely frustrating. I would like to have a configuration bundle with all of these vetted settings in place, but I cannot seem to get it organized even with attempts at work arounds. Is there any thorough documentation on how profiles, settings, and projects work in PrusaSlicer?
