Forms personalizations

 I am trying to personalize the HRMS person form PERWSHRG which is called from a modified task flow . I have to make most data items view only with only a few specific items that can be updated by users.

This seems to be working correctly but there are a few dates that I cannot seem to change the attributes of:

the are specifically Adoption Date, Adjusted Service date, Date of Death and DSS Linking Letter End date.

has anyone else had any rpoblems with these dates?
