Hi all!
it is very strange bug\issue and i don't know how to reproduce it, but description is next:
we have some created issue, we work on it, but when it is a time to close it - we have no button "Resolve".
We have a lot of another issues in the same project ( with same permission scheme and with same workflow scheme) and all is OK for them. We have just one way how to resolve it: we make a clone, then delete this issue and close cloned issue.
We haven't do nothing special to this issue to occure such bug.
i use "permission checker" an it says that i have permission to resolve this issue, but "resolve button" is not visible for me 
Could You please advice something?
Thank You in advance for any help!
