Fritz 19 won't load the main opening tree

This message is for everyone who has Fritz 19, the chess playing software by Chessbase.

Everytime I load Fritz 19 in classical mode, it loads the Personality-All Around opening tree no matter what.

It is apparently supposed to load the main opening tree Fritz 19.ctg when you start in Classical Mode, and only use the Personality Books in Easy game mode, but it doesn't do that.

Even if I uninstall the program, and reinstall, it loads that opening book on start up.

If I manually load the Fritz19.ctg opening tree, the next time I start the program it still loads Personality-All Around no matter what. So this means everytime I run the program I have to reload the opening tree each and everytime, which is obviously inconvenient and annoying.

Does anyone have this issue, and do you know how to fix it?
