Half of the labels disappeared

[Dark Waves]

Thanks, Jesse.  As you suggested, I've stopped trying to get my whole list into both MRCCs and just added the devices that will be directly connected to each unit, and so far that's improved results, insofar as there aren't blanks commencing partway through the list, although in both there are one or two gibberish entries, such as the recurring "ghij" label.  In both lists I've added fewer than 15 labels.

I've just sent the email you requested, and I'll look to see if I have another SD card to try also.
