Imported XMI from Enterprise Architect: documentation not showing up

I am evaluating Visual Paradigm for UML and I am importing an xmi document that was created with Enterprise Architect. I am relatively new to it so I may not be aware of certain features or settings, but the documentation in the xmi file is not showing up in Visual paradigm.

If I click on Open Specification on a class or attribute the Documentation text field on the General tab is empty.

The document is confidential so I cannot post it here, but here is a sample of the formatting:
<element … xmi:type=“uml:Class” name=“XXX”>
<model package=…
<properties documentation=“Docs not showing up” …/>


<attribute … name=“XXX” …>
