I have just upgraded my dev site to 12.3 and nodes that have umbracoNaviHide set as true in the backoffice are returning as false in the UI so are now appearing in my navbar? Anyone else getting this or have any ideas what has gone wrong?

Could be something to do with https://discord.com/channels/869656431308189746/1170100786693419129/1170657219453390909 - given it’s a bool, the default value would be ‘false’

Very possibly, I will check the language settings on the properties
