Additional information
This issue has occurred since the initial release of GIMP 2.10. I initially downloaded and installed directly from the website. I've reformatted my computer entirely since then. The only way I've been able to successfully use GIMP 2.10 since its release has been by exporting the image and alpha as distinct images and merging them with ImageMagick.
