It appears this misalignment is an issue in the 2018 version. In the 2016 version I'm having a different issue - the overlay appears to be aligned, but it won't show the range of values in the image. I'm trying to overlay a map of T-stats that I know range between -6 and 6, but I'm getting 1 color. 
Help with either of these issues would be great - misalignment but proper values in 2018, proper alignment but not showing range of values in 2016.
Thanks
