Hey! How do I remove the wrong releases from the release list?
Sorry for the late pick. Did you solve the problem meanwhile?
Once you sign into the contributor portal, click the 'Uploaded Files' tab.
From there, click the 'Releases' tab.
You should see a list of all of your releases there. The far right column is labeled "Visible when indexing." Find the invalid releases you no longer want visible and check the adjacent box that says "Hide".
That should do the trick.
