Thanks for fixing the links.
I tried to reproduce my problem, and it does persist in 1.0.8. i.e. the section at the bottom of the board settings for “linked page metadata” just breaks after first use: no entry field, no way to add more fields; nothing at all after the explanation (i.e. the line that ends…“labels can be hidden altogether.”).
Even worse, the kanban board view is now completely blank, even though the markdown seems clean. Only a full app restart shows the board again. and there’s still no way to change or edit the “linked page metadata”.
If I remove all “linked page metadata” from the markdown and restart Obsidian, the board goes back to normal and is usable. But the second I try to use the feature, things screw up again.
On my system at least, it’s a serious bug.
Weird, though I hope it makes sense to you!
