Hey Gmanroberts1 - I found your conversation on Charlotte KCLT for MSFS support (fsdreamteam.com). I tried the solution recommended by the moderator, moving the static aircraft package line to the end of the CONTENT.XML file and it fixed the issue with KCLT and the static aircraft mod.
For reference, the CONTENT.XML file is located here:
%LOCALAPPDATA%\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache ( MS Store version )
%APPDATA%\Microsoft Flight Simulator ( Steam version )
I used Notepad++ to make the modification. Highlight the line referencing the LVFR static aircraft mod and use Shift+Ctrl+down arrow (repeatedly) to moved the line to the end of the file.
