Re-enable Scheduled Refresh Following 4 Failures

Hi

I'm trying to re-enable a scheduled refresh of Semantic Model that has been disabled following four consecutive errors. 

The error states "Please resolve the error and then re-enable".

The errors have been fixed and the report has been published to the service.  I cannot get to a point where I can re-enable the current schedule or delete the current schedule and create a new one.

Any ideas would be great.  Thanks in advance.
