Hi!
Somewhat new to release management in Jira and have come upon something we think is a bit strange. There seems to be a difference between which issues are considered "unresolved" when release a version from the list of unrelease versions compared to when clicking release from within that version.
To clarify. Pop-up that is shown when clicking on the hamburger menu on the right in the list of releases. Note that it says there is 16 unresolved issues (which in our mind is correct as there are 16 issues with this fix version that is not in the Done column (right most column in our Kanban))

Opening the version and clicking on the "Release" button in the top-right cornor shows this pop-up. Here it says that the no. of unresolved issues are 51 (all issues that are tagged with this version). Even more note worthy is this is not the same as displayed on the version, you see in the background on the picture below that it says 35 issues done and 16 issues to do.

NB: it seems it's not only a matter of display either. When we released a version 2 weeks we did it this way and all issues with the version was moved to the version we selected (not only the "issues to do".
