Steps to reproduce:
1) log in (admin siteaccess) with the admin user;
2) edit or create a role (in "User accounts/Role list");
3) create a new policy (or edit an existing one) on module "content" and limited to a single function with function limitations (e.g.: "create", "edit" or "read");
4) select a value (different from "Any") for all the function limitations;
5) add a node limitation to some node of the content structure or media library;
6) when You go back from the node selection to the policy creation, the values You have selected in step 4 for "Section" and "ParentClass" have been reset to "Any".

Expected result:
in step 6 the values selected in previous step 4 must been retained.
