Process Builder - Cannot create new process because of Naming Conflict

Hi,

I am trying to create a New Process in Anaplan Process Builder. After entering a Name and selecting a Model, when I click on Finish, I get this error message:

"There is a naming conflict with your model structures."

In the target model, we have used standard naming conventions and don't see any conflicting names. What might be causing this error and where should i look to fix this?

Thanks
