Steps to Reproduce
Issue not reliably reproducible because sys_ui_list entries are normally created as expected by non-admin users.
If this issue occurs, create a business rule to stop the sys_ui_list table from unwanted update or insert operations.
For example, to set the Default view list layout to be updated only by users with the admin role, the business rule should state that before update and insert on that table, the update should be cancelled if the user doesn't have the admin role.
PRB647812-workaround.xml file provides an example that can be modified and imported in the affected instance. The array in line 13 should be reviewed to add/change/remove the roles that should be able to update the Default view list layout.
