Can't save my entry in 'Properties'

I can’t seem to save my properties entries at all.
I’m attaching a screen grab when I tried to create ‘in-progress’ and then it would not save at all.

How do I get this to work?
Thanks for you help!

Things I have tried

I’ve searched through the existing messages about Properties but nothing matches my issue

This looks like something to do with the MAKE.md community plugin and not Obsidian’s Properties.

They have a Discord server (linked from their homepage). You may get some quick help over there.
