BUG: New Card Visual - Details measure disappears when publishing

I have a formatted measure in my details under reference labels (using FORMAT measure). The measure works just fine in Power BI Desktop, but when I publish the report, the measure is removed and I just get the '--' displayed.

When I try to re-add the measure, the visual breaks, saying: Can not display the measure right now. All formating options are no longer shown and removing the measure does not fix it.

This is also happening to other reports I published before, that were working fine until a few days ago.
