Wow, that was a challenge.
I use freezer paper all the time, but never have used the glue stick. Sometimes,I have stitched the freezer paper when I caught the edge of the paper with my stitches. I prefer, instead of cutting the back when I have a little over an inch left to stitch down, I pull it out from the side. I have done this for 20 years without using glue stick. I have also cut the back, just prefer pulling out the freezer paper without cutting the fabric. But I also hand applique.
