Rank and Participants not accepted in Dashboard gadget since Jira update

https://jira.reactos.org/issues/?filter=10001

However when adding a "Filter Results" gadget to the Dashboard, it fails with

The selected filter filter-10001 has an error: Field 'Participants' does not exist or you do not have permission to view it..
The selected filter filter-10001 has an error: Not able to sort using field 'Rank'..
