How to align text with non-continuous label?

Hello, I am an Xamarin app developer creating an iOS app that will print labels using a Zebra Printer (ZQ510).  I am trying to print the following text onto a label:

Best Buy Date
00/00/00
SomeProductName

However the printer doesn't seem to detect the gap between the labels as it should when using MNW (Media Tracking, Web). It prints as if it is continuous and the text is scattered all over the labels/gaps. The labels are 1.25x1 inch labels (peel off stickers).

Here is my ZPL:

^XA ^MNW ^MMT ^FX Example of comment ^CFA,30 ^FS ^FO0,30 ^FDBest By Date ^FS) ^FS ^FO0,60 ^FD11/23/2016 ^FS) ^FS ^FO0,90 ^FD Clams ^FS) ^CFA,30 ^XZ

I've looked over the documentation here: https://www.zebra.com/content/dam/zebra/manuals/en-us/software/zpl-zbi2-pm-en.pdf

but couldn't identify what I was doing wrong.  I'm very new to ZPL, any help is appreciated!
