It adds an "All Data" filter by modifying the `CaseListMixin` class that is subclassed by `CaseListReport`. I've examined the code of `CaseListReport`'s descendants, and none of them seem to cause conflicts with the changes made.
You should remove this import and point the remaining references to `ExpandedMobileWorkerFilterWithAllData`
