[MapProxy] Trouble reprojecting EPSG:4326 WMTS to EPSG:3857

I'm trying to use WMTS data provided by NASA
(https://earthdata.nasa.gov/about-eosdis/system-description/global-imagery-browse-services-gibs)
that is available in EPSG:4326. To overlay it with my base map, I'm
following the example in the documentation to reproject it to
EPSG:3857. However, the resulting map is coming out scaled up by 125%.
The only way I've discover to fix this is by scaling the bbox in the
grid definition down by 125%, but that means that the last 25% of the
globe is chopped off. Has anyone else encountered this kind of
problem? Here's my conf.yaml file:
