Pixel Mapping on WwCw LED Tape

I'm trying to make a pixel map for my show with some LED WwCw fixtures, and I'm at a loss for why it isn't working. I've assigned the patched channels to the pixel map. I have full control of those channels in the regular live table. I've patched the server channel, media channel, and effect channel. I have the server channel and the media channel at full. I have crossfade set to -100. I can see the effect I want in pixel map preview.

I've even made a separate pixel map with the backlights that does everything I want it to, but when I recall the values from that server channel and media channel into this pixel map of LED tape, nothing. They just sit in their background values.

Any ideas?
