I am making a model i SAC on imported data from a CSV.
When I initially is making the model, it looks like this:

Here my dimension is named Object_Type_Operational
But when I then create the actual model, it changes:

I have read somewhere that you cannot change the name of the dimension once it is created, and if true, how can I avoid this renaming of dimensions?
Because it is rather annoying, and not very user friendly
