What went wrong?
- I can no longer re-order tabs within any of my Categories. I checked the STASH files and the tab order (displayOrder attribute) of newly created tabs is 0 (conflicts with the existing tab 0 which is the 1st tab).
- I even tried manually editing the displayOrder of every single tab (15 files, ensuring it went from 0 to 14) to see if hand-editing displayOrder would fix it, but the new tab still shows at the end.
