I have a structure with about 20 issues in it. All of these tasks are from a single project. I now need to add issues from another project, but anything I type in the search bar returns "No issues found." For example, if I do a JQL search for "project=mgd," which is a project that has over 100 issues, it returns "No issues found" and there is no option for searching outside of the structure. If I perform the same search but for the project that is already part of the structure, I see results for tasks within and without the structure.
Performing a text search for "the" gives the same results.
Is there something limiting access to only one project?
