why when using any "resolution not in xxxxxxxx" also hides unresolved

[Deleted user]

Basically if I try to filter duplicate or invalid issues it also hides all that have resoltuion is unresolved. Is it a bug? And can I fix this in any better way that just using "resolution in" for all the other possebilitys of resolution?

As I can't comment on the answer below..here it is:

Thank you for clarifying, I guess my logic was a little off then as I assumed "unresolved" counted just like other listed options. Is there a good way to not show invalid/duplicate while still listing all others including unresolved?

It's hard to say what is going wrong here, as we don't know what your JQL is.

Resolution is probably working correctly though.  A select for "resolution not in x" implies that you are looking for stuff that has a resolution, but not when it is X.  So it ignores unresolved as that means "no resolution set".  It's like saying "show me all the cars, except the red ones".  When it's unresolved, there isn't a car to have a colour, so you can't select it with "all the cars".
