Bulk-change Linking to Parent Issue

[Werner Schott]

I've been trying to bulk upload detailed requirements and link them to existing high-level requirements. I know there are 'good' articles that show this, but in my case they didn't work. So I'm trying the next best thing - bulk-change uploaded requirements to link them to a parent, but when I go and do this, the 'Edit' screen does not find the issue. Even though it does exist, as when I go into the issue, I can link it to the parent there - just not in bulk change. Is there a way to make this easier?

No Matching Parent in Bulk-Change:

However in the Issue edit, it finds the parent.
