Unofficial Achievement Set displaying in Developer's Developed Sets

[TwosomesUP]

Describe the bug
When viewing my Developed Sets page, an Unofficial Achievement Set is showing up in the list. In this case, it's Deathsmiles: Mega Black Label.

To Reproduce
Steps to reproduce the behavior:

1. Go to TwosomesUP's Developed Sets page (https://retroachievements.org/user/TwosomesUP/developer/sets?filter%5Bconsole%5D=true)
2. No specific filters, but I used Sort By: Title, and Group by console

Expected behavior
I believe only Official sets should appear in this list. I have a few other sets in Unofficial and they do not appear.

Screenshots

Desktop (please complete the following information):

• OS: Windows 11
• Browser: Chrome
• Version: 126.0.6478.127 (Official Build) (32-bit)

Additional context
I thought it might have been due to it having published leaderboards, but a few of my other Unofficial sets have leaderboards as well, and they don't seem to be causing any issues. Also, the Unofficial Set that's appearing is currently marked as a "Special Claim"

I would assume anything that has published leaderboards you've authored should be visible here, regardless of claim status.

This leads me to believe Deathsmiles: Mega Black Label is correctly appearing. The incorrect behavior is the other games you've mentioned which have published leaderboards are not appearing.

I don't know if this is related directly to this issue but I've noticed a few devs have Gamecube games listed in their sets list, but most of us do not.

Mine as an example where none are listed, but do have leaderboards submitted:
