I attached a PDF of a report that I have that generates a list of saved preferences. In the Plan & Profile Generator were two - Default and whatever strukton is.

I loaded this into Notepad++ and it found no detectable errors. I also loaded it into InRoads Ss4 and was able to call up both preferences and it also allowed me to save one as test.
I was also able to load a profile preference and save it as test and then make it so the preference strukton loads the original profile preference on the Profile Controls tab and make my "test" preference load the new "test" profile preference.
Hopefully someone from Bentley Civil can run some diagnostics on the process and figure out the issue.
