I am working on a company-managed project and created a scrum board.
I can see some issues but not others in my backlog (roughly 30 out of 95 missing). I have checked my filter and all seem to be appearing there: I have set the filter to display all issues in a certain fix version.
I can see there seem to be various issues causing this, but I am not sure what else to check? To my knowledge, all issues are following the same workflow, In one case, one issue is appearing fine but its clone (which I believe has all the same field settings bar a label) does not appear.
I've checked my columns and haven't any issues with an Unmapped status

Thanks for any advice,
Laura
