I had to reinstall WoW this week and afterwards, this addon is missing the Extra and Saved tabs. I've tried several things, uninstalling and reinstalling and it is missing on all my characters. The Dressing room features are working as intended.

I compared my Better Wardrobe folder with a friends that was working and noticed I was missing modules. So I deleted my Better Wardrobe folder and used the "Download" instead of "Install" and that fixed the issue. All the missing modules were present and my missing tabs were back.
