Some entries may require account privileges beyond what a standard user would have. For information, see the "Editing PC-DMIS Entries" topic. That topic discusses the different account privileges. It also provides a description of each icon that appears next to each entry in the PC-DMIS Settings Editor.
You may see two sections with the same base name, but one with a prefix of "USER_", for example USER_AutoFeatures.
Settings that require a general user privilege to change them are stored in these sections.
Interface settings that require administrator privileges to change them are stored in the regular section name, for example AutoFeatures.
