Namespace of shared attributes are being messed up

Scenario

I have two DMN files. In the first one, I define a data type. In the second one, I want to model a decisiontable. 

I import the data type from the first file into the second file. I need to supply a name, for which I add "shared". 

Then, in the second file, I add a DMN input data symbol. In the properties of it, I select the data type of the first file, whith shows as "shared.Person", which is what I would expect as name.

Now I craft a DMN decision and make sure the input data is connected.

Then I set the type of the decision, and select 'decision table' as the expression.

What I expected

The attributes from the shared data type should be shown as <name>.<attributeName>

What happend instead

The attributes from the shared data type are shown as <name>.shared.<attributeName>
