Problem:
Edited UCR default policies got overwritten during an update.
Environment
You have used the default policies to configure your UCS domain and changed some settings in these policies to match your needs.
After an update all values are reset to default and your changes are lost.
Solution
UCS default policies will get overwritten during an update if there are newer version of these policies. You should create a new policy with your desired settings and assignd these policies to your objects. These non-default policies will not get lost during an update.
