After a server reboot and booting a client six lines of settings were added to "MVPSpecificSettings" and in the several days use since then no extra settings have been added to "MVPSpecificSettings"!

There was an old bug fixed a couple of releases ago, but it didn't remove any incorrect entries that were already there. It's likely all those garbage lines were added a long time ago on your machine, and the problem is no longer happening.
