The synchronization problem has been resolved. All JQL Functions are working as expected in Enhanced Search Filters and the filters are being synchronized successfully.

We believe we have resolved the problem and Enhanced Search Filters are now synchronizing successfully. We will continue to monitor the process.

We have identified a possible root cause and are rolling out a fix shortly.

We have identified a problem with the synchronization of Enhanced Search Filters which is causing a number of customfield related errors to appear against all filters in the Enhanced Search page. Agile boards powered by these filters will be out-of-date. Our logging indicates that the synchronization process has been broken since 01:00 and only affects filters with the dateCompare, issueFieldMatch and issueFieldExactMatch JQL functions.
