Text property on UD1

We use Text3 property of UD1 members to save Status of the member (member is a change request). We are having an issue with this approach. When we create a new member, we set its Text3 property for scenario type and Time to "Draft". If we change the value to some other status via rule or manually, it saves it fine. When we create a new member or update an existing UD1 member (any change in member properties) the value of all existing members reverts back to "Draft". Does anyone have any idea how to fix this issue. We are using 7.2.4 version.
