Model after function not working properly 25.08 patch

Summary:

We have multiple hierarchy sets attached to one dimension.

When we use the model after function on existing value it copies the hierarchy mappings from the original value into the request for the new value I am creating.

For hierarchies we do not allow users to add values only insert new values we added to the dimension.

The model after function in 25.08 patch is generating a add command to the first hierarchy set and insert to all other hierarchy sets attached to the dimension. This new model after request is now failing validation as it is trying to add to a hierarchy instead of insert.
