I've created a new project (Features/FET) and migrated tickets to this project. All workflows and configurations work as designed.
However, when I search for issues using project = Features I get results from a completely different project (Product Management/PMP)!
Using the project key FET in the JQL returns the correct results. Selecting the project in basic search mode returns the correct results.
This only happens when using JQL and the project name (with or without quotation marks around "features"). If I switch back to basic mode after doing the search in advanced, the incorrect project (PMP) is selected in the dropdown.
Re-indexing did not resolve the problem.
Help!
