Trying to Duplicate Project, Says it's Branded

I'm trying to duplicate projects to another account for work because they were previously on my personal account, but it keeps telling me the projects are branded and only owners can duplicate branded projects. 

The thing is, the projects USED to be branded, but I deleted the brand so it really shouldn't be branded as the brand doesn't even exist anymore. I went through settings and saw nothing that indicated it was still branded after I deleted the brand. But it still says it's branded and I just can't duplicate them because it keeps saying it's branded.

Anyone know how to fix this?

Edit: I removed the elements associated with the brand, but now it keeps telling me that the brand that the project was associated with no longer exists, so when I share it with the work account, it says to ask the owner to share the project again since the brand associated with the project doesn't exist anymore. I share it again, but keep getting this same message. I just wanted to remove the brand so I could allow the work account to duplicate the project. Why is this so hard?
