The default APN settings for my phone have to be changed but I cannot edit the APNs

Since installing Marshmallow on my Zenfone 2, I cannot edit my APNs. After entering the changes to the default values, it tells me "APN settings are not available for this user". I use Tracfone as my supplier.

Moved from the Marshmallow forum to the Zenfone 2 forum, since this is likely a device-specific issue.
