Random Content Moderation?

I am working on a game that allows you to build using 5 stud square blocks and I got a content moderation for an image similar to the one below but I’m not sure how. It seemed to be fine with the one I’m sharing and the only difference is the name and the color of the asset. I was trying to find a way to get my images to be crisp and neat for my inventory UI so I found that creating the asset, publishing it, and then saving the image that Roblox produces does the trick. I am using an image produced by Roblox but I’m using it on my game on the Roblox platform. Is this an issue or did I get hit with a random content moderation? I have several items like this but this was the only one they moderated.

Here is the image of what the green one looked like (except for the color of course):
