Oh my god I am so sorry. I found out why that random panda model was popping up. I had a script saved where I could copy and paste it into the command bar and bring in any item from the catalog using the item numbers. I had the panda models numbers pre filled in there so all I had to do was replace those with whatever I was trying to import. And that was the issue this whole time, it was just running that script!
Really sorry for wasting your time, thank you for trying to help!
