Today I printed a heat tower and sliced it in cura - no issues - loaded a second heat tower after adjusting settings cura listed 3 files on import and said they were corrupted and that I must reset to default settings. So I did. Afterwards, I cannot see the entire model anymore in cura. Here is what I am seeing and the project files associated as well as my full cura screenshot screen for settings etc.
Printing on Ender 3 Pro with PLA.
