My Sprint Filter is suddenly showing incorrect tickets

[Jon_Fister]

Here is my filter:

project = LG AND issuetype in (Action, Bug, "Client Onboarding", Improvement, Task) AND status in (Analysis, Backlog, Blocked, Done, Open, "Ready for QA") AND fixVersion in (EMPTY, unreleasedVersions(), releasedVersions()) AND (resolutiondate <= -2w OR resolution = Unresolved) ORDER BY Rank ASC

I'm fairly certain that last week or so this was showing the correct tickets, now all of a sudden in my done column, which should only be displaying things resolved the past 2 weeks, is specifically NOT showing things resolved in the past 2 weeks and is displaying things clearly resolved months ago. 2 Tickets to be precise.

It looks like to me that the fix version section is pointless, but I trusted that I put it in for a reason (JIRA is finicky and I don't want to break anything...like this issue). I did try removing it, to no avail. 

P.S. I don't know if it's related but our product owner said he was seeing weird behaviour in the backlog where tickets that are months old (as in completed months ago) are showing up.

I figured out something that fixed it for me. I still have absolutely no clue as to why this happened in the first place, however this is my new filter:

project = LG AND issuetype in (Action, Bug, "Client Onboarding", Improvement, Task) AND status in (Analysis, Backlog, Blocked, Done, Open, "Ready for QA") AND sprint in openSprints ()

I removed fixversion as it was useless, and replaced resolutiondate and resolution with sprint in openSprints () and all of the appropriate cards are now displaying.

Nevermind, for some reason the sprint board filter applies to every single sprint, inclusive of the backlog, in the entire project. The above filter makes the backlog empty. Looking for a new solution.

Here is the resolution date for a ticket that is displaying with that filter:

Here is the resolution date for a ticket that is not displaying with that filter:

As you can see, this logically seems completely backwards.

I've removed the two cards that are completely out of the 2 week resolution date period from the sprint and they're gone from the done column (don't know how they were ever in the sprint), however now I have an empty done column.

I have done a manual search using the following query:
project = LG AND issuetype in (Action, Bug, "Client Onboarding", Improvement, Task) AND status = Done AND Sprint = 28 AND (resolved >= -2w OR resolution = unresolved)

As you can see this is essentially the same as the one in the original post. However I can the see the issues I'm meant to see when I do this search.
