Hello there @nwhiggins, we suspect this is an Elements issue, but I am going to download and troubleshoot and I will let you know shortly our findings. Do you have access to another version of Photoshop?
When you open the template you should have access to all of the tee layers and you can switch on the color you want and delete all the others to make your submission file smaller.

We do prefer to have all colors on separate layers. Here are some other tips you’ll find for prepping your artwork for submission:
