Name Stealing Bug - Unable to change back to previous RSN

There is currently a bug in game causing players to be unable to change their RSN back to their previous RSN even within the 35 day reservation period. I was due to change my name back to my main RSN last week, however I was met with an error message stating that the name is unavailable. The name is still listed as my previous name and has not yet exceeded the 35 day reservation period, so it should not be released.

I have been in contact with several other players who are experiencing the same issue and some are nearing the dates that their names can be released.
Somehow, the previous RSN's can be hijacked immediately after a name change. For reference, one of the affected players previous RSN was able to be taken within 12 hours of their name change and can now be added as a separate account even though it displays as their previous RSN. If you add their current RSN and their previous RSN, it merges the two accounts into one add on the friends list.

A few weeks ago there was a name change bug in game that enabled players to take any name, even banned or active names. This is the first name change attempt back to our previous RSN's since that bug and we have been unable to do so. Could possibly be an unintentional error due to that bug.

I can provide further screenshots and videos of this bug if required.
