Object User Attribute 1 & 2 ErrorMessages renaming Project Data User Attributes

[Anonymous]

See attached snapshots

I'd like to use the model object user attribute 1 to display marking plan however it also changes the user attribute 1 in Project Data to marking plan

Is there a way to rename the Model object User Attribute 1 & 2 boxes without changing the Project Data User attribute names as well?

no, therefore the same errormessage is used. So this is always the same.
