After applying a recent patch in our SharePoint environment, I've encountered an issue with Managed Metadata fields. When selecting a document, the actual values of these fields no longer appear in the information panel. Instead, a number is displayed (which I assume is the internal representation of the value).
The values are displayed correctly in edit mode, and it is possible to save and edit the values as normal. Also, this issue only seems to occur with fields that are set as required.
Is this a known issue, and is there any fix? Or is this a bug introduced by the latest patch?
We are using SharePoint SE (on premise).
Thanks in advance.
