Can you please disable all addons except dugiguides and try again.
Ensure that you have updated all your addons, in the Addons view in Character Select screen, ensure that Load Out of Date AddOns is unchecked, then uncheck Out of Date AddOns.
To this day most AddOn developers are slowly updating their addons since the release of 10.1.5.
If you still got issues, try /dugi fix, if that still doesn’t work try reinstalling the guides using the Installer. Ignore the Announcement post for 10.1.0. Ensure that the version you install is 9.0221.
I hope you get this resolved 👍😉
