cosmetic? byte-shift in radio diagnostics page, and erroneous version numbers

It's not unusual for there to be an erroneous Mesh Extender id in the Radio Diagnostics page, whereby the SID has been shifted by 2-8 characters to the left or to the right (and backfilled). E.g. in the image at https://www.dropbox.com/s/cd4ubojswbny9e6/IMG_20171118_144325.jpg?dl=0 you can see that the two correct SIDs are 2caf956f3b61 and a7cb6a5b7a8f, and the second two rows are shifted versions.

This may (or may not) be related to the erroneous (very large, negative) version numbers that are showing in the "Current Bundles being received" section.

Not top priority as we know to check for shifted SIDs, but should be investigated at some point.
