I was able to get some confirmation that there should be nothing wrong with the TMNT assets I am using in my project since they are from the approved assets list. I put in a separate thread about this in the feedback section but now that I have confirmation this is likely a bug, I am putting a ticket here. Here is the original thread:

What Type of Bug are you experiencing?
Assets
Steps to Reproduce
Use TMNT approved icons of the 4x Turtles on textures in your TMNT island. Launch a session, wait. You will soon get a Moderation Warning
Expected Result
Using the approved TMNT assets should not result in a moderation warning
Observed Result
I’m receiving a moderation warning when I use assets of the 4x turtles that are from the approved assets list
I’m also encountering this issue - the assets being flagged are just the large outfit icons for the turtles (e.g. T-Soldier-Hero-QuietPeanuts-L). I went through the appeal process for the initial violation and the sanction was upheld on review. The moderation system continues to be profoundly flawed.
