[Galaxy S6 Themes and Apps] lizaSB:
I don't know for certain which one of these is responsible. My gut says this one:

<CscFeature_Wifi_ConfigMifLockForHWRev>11</CscFeature_Wifi_ConfigMifLockForHWRev>

or this one:

<CscFeature_RIL_RemoveDuplicatedNetDuringManualSearch>TRUE</CscFeature_RIL_RemoveDuplicatedNetDuringManualSearch>

Otherwise, here are the default strings in my csc, one of them is surely responsible:
