HOW THIS IS POSSIBLE? :A DUPLICATE OF A CATEGORY HAS BEEN CREATED IN .RVT

[IbrahimNaeem]

Dear All,

I'm solving a corrupted file on 2015 version and it has opened but failed to save. on looking at the journal file, I realized a duplicate of category exist, how to solve this bug? AFAIK, One can't add or delete Revit Categories so how did get birth in the Revit Document    

Thanks, Ibrahim Naeem

Firstly, it is not a bug. Even if you try the categories node on an empty template, there are some duplicates. (e.g. Analytical Surfaces, etc)

As far as I know View Reference is not an actual Category, which means if you look up Revit categories using its API, there is no such category.

I think that specific Dynamo node shows the family name when the element has no category. 

Note: there are several elements in Revit with no actual category. such as Views, Text, Dimension Styles, Elevation and Section Tags, etc

May be I'm giving a wrong instance out of dynamo but I have a warning in the journal file while writing the file saying there's a category gotta duplicated!
