Can you please ensure that the guides were removed properly by using the Dugi Installer > Settings > Repair button Okay x3
Click Okay then click Reinstall.
If you did this can you please do it again.
Use Curse app and right click on the Titan Panel Classic and click Delete Settings (Saved Variables) then relaunch WOW.

Any other information you can provide will be helpful.

Looks like the Repair and Re-install setting steps  and the Curse App (Actually Chocolate Bar Panel) Delete Settings (Saved Variables) did the trick.
