Steps to reproduce

1) create 3 repos and 3 distributions (more than 1 would be enough) and a namespace (ns_test_b7d78d17)

2) upload new artifact collection_dep_a_68efd70f version 0.0.1 (to staging)

3) use the modify endpoint to put the content units to these 3 repos

4) login to UI and go to this url:

(namespace name, collection name and version are irrelevant)
http://localhost:8002/ui/ns_test_b7d78d17/collection_dep_a_68efd70f/?version=0.0.1

check screenshots: Version menu shows 4 identical results. If one of the collections is signed, this menu keeps showing them all as unsigned.
