In cross projects, searching for Requirement fix version does not return results

Context
1 Project for requirements with version REL ; 1 Project for tests with version REL.
(same name)
3 tests from project Test linked to a Story from REQ project.

Steps to reproduce:
Create a test execution / test plan;
Add tests
Filter by Requirement fix version.
Search for version REL from project Requirements -> Search returned no results

Search for version REL from project Tests - > Return tests

It should appear results in the first search (REQS project) and not in the second one (TEST project)
