Blank TF Preferences window

Running macOS Sierra 10.12.6, TotalFinder 1.9.6. Almost every time I try to open TF Preferences, I get a blank white window, and then the Finder seems to go off in the weeds. After I restart FInder, everything is fine again. SIP is disabled. Any ideas?

Could it be similar to this issue?:
