If I enable something in the Extras and apply, It will not show in the Entries until I restart the dialog. 1) Open the settings and confirm the Entries are all there. 2) Disable/Enable something from the extras. 3) Apply. 4) check the entries. -> the entry was not removed or added. Note, sometimes, they're all gone. See: https://bugs.kde.org/show_bug.cgi?id=390890
I cannot reproduce, probably fixed as part of BUG 390890
