Error with Duplicate object name

space

While comparing my dev environment to my other environments I get this error. A duplicate object name has been found. This may occur if the SQL Server that you are registering is case sensitive but the case sensitive option is not set. If I set the use case-sensitive object definition I get another error Value cannot be null parameter name key: it stops in the reading parameter step. The only difference between dev and the other environments is there are snapshots with other names. Could this be the issue? Any assistance anyone could provide would be greatly appreciated.
