We set up the worksheet in our template file, so every file we work in has the same layers. I tried formatting the column to show the image at a custom scale. It changes the size of the cells, but still no image shows up... so that makes it almost seem like it's there but you can't see it?
Additionally, the symbol I'm using is the same between files because they are also in our template. So that makes it a bit more perplexing that it works in one file and not the other.
