[MSCE U16.2] Item Types expression not updated

I have an Item Type containing properties that uses an expression to display Sheet information (name, number).

If I place a text field using this info it will display the correct data but if I update the Sheet info the fields are not updated (I've executed FIELD UPDATE ALL and model properties Update Fields Automatic).

Existing and reopen the file will update the fields.

Test file attached.
