Hi, I have an issue where the backlog view is not reliably showing issues.
I have issues with a parent that is an epic (PSD-51). When I show the epic panel in the backlog and I click on the epic it is only showing 16 out of 17 issues.

What is interesting is that when I hover my mouse over the Epic, it shows the correct issue count.
If I go to the List view and filter on the parent as epic PSD-51 - then all 17 issues show.

So, the missing issue from the board view is PSD-260.
If I move PSD-260 from DONE > IN PROGRESS … is now shows on the board:

Move it back to DONE… and it no longer shows?

However, there are many other issues that are in the DONE status showing?
I tried searching for how I can view/edit the underlying filter on my backlog, but I don't seem to have that option in the ... menu.
Any assistance would be appreciated.
