Simulink.MDLInfo not stroting input and output block name

Hi, I'm using masks to define custom input/output blocks, by doing this i hide the names of input/output blocks. This lead to a bizare behaviour of the MDLInfo class. - Whet I show the Input/Output block name, the onformations about these blocks (names) are stored in MDLInfo, so i can access thiss information without loading the model. - The issue is that when I hide the Input/Output blocks, MDLInfo class return empty fields as Input/Output Information.

Is there any solution to work arround this ?!

Thank you.
