First time coming over to the SharePoint area here. I'm experiencing an issue with our company's team site. We've set up custom managed metadata fields which use a closed term set. Changes cannot be made to the term set except by admins.
Using 'Classic SharePoint' (the old interface), we were able to leave these fields blank, but with the new SharePoint interface (or the underlying changes) we are no longer able to leave these fields blank. The columns are set up to be optional, so input should not be required.
I've tried going back to the 'Classic SharePoint' site and can confirm that it is possible to set this field as blank with no error messages produced. This only occurs with the new interface, but if Microsoft is phasing the old interface out, then our site will have to work as intended with the new interface.
Is there any workaround for this, or is it something for Microsoft to fix?
