Sharepoint List Formatting - JSON not being retained

[ooABoo]

I have several MS Teams lists form views formatted in JSON. If i edit any of the fields, the formatting is lost. If i refresh/reload the list, its back again.

Is this a feature or some temporary glitch? I dont recall seeing the issue before.

Rebooting fixed the issue so im presuming it was a cache issue.

Spoke too soon, formatting still disappearing..

Browser cache cleared but no chnage, any ideas?
