Got a similar situation, with slightly different angle. In my case the issue is not in the numbers but in the release of funds that are confirmed to exist. FAB committed in writing to reprocess my payment after Hyperwallet migration, I fulfilled every step, and the response has been an moved to a “Finance team” with no ETA or details. The dashboard opacity you describe and the payment withholding I am experiencing feel like symptoms of the same underlying lack of accountability. And total communication fail between all relevent parties. Especially prominent and shocking is the lack of communication between Epic Games and Fab.
Was anybody of you able to make any progress?
