VISA skips certain commands

I'm writing a small automation script for a Tektronix DSA8200 Oscilloscope. Part of my script involves setting up the MATH channels 1-4 and setting their vertical position and scale. Then, it's supposed to set reference 1 to math1. However, the scope has been skipping these steps. I've used NI I/O Trace to make sure that the commands are being sent without error, which they are. They just don't actually happen on the scope. I am able to use the NI communicator to manually run the operations after the script has completed, and they work just fine. I've tried setting "*WAI" all around my different commands trying to see if there's a SYNC issue, but it's done nothing. What could be happening? 

 

I've included my nitrace file in case that helps at all.
