"Hide completed issues older than" setting on Jira Software Kanban Boards

[Matthew Stublefield]

Can anyone say definitively what this setting does? Does it:

1. Hide issues from the board when there has been no activity on them for more than X weeks and they are in the right-most column?
2. Hide issues from the board when there has been no activity on them for more than X weeks and they have a resolution set?
3. Hide issues from the board when there has been no activity on them for more than X weeks and they have both a resolution set and are in the right-most column?

Update:  I upgraded to version 7.0.10 and initially it fixed my issue above, but now a few days later its not working.  My test environment is working just fine no issues.
