[Solved] Problem Saving/Loading calibrated lights from Fuji X-Trans sensor

I'm using a Fuji XT-1, which uses the X-Trans sensor, doing the calibration workflow from the RAF files to a final integrated frame works flawlessly. I ran into a problem, where I wanted to save the fully calibrated light files so I don't need to calibrate ALL files again when I capture more data on this subject. I calibrated the lights and saved them (as fits). When I load one of these calibrated lights, the image is not properly debayered. When I open the calibrated fits file in ImageJ, the X-Trans pattern is clearly visible (as expected) and the CFA pattern is correctly called out in the HDU, pasted below for convenience. I believe what might be happening is that there's some ambiguity about which end of the image in the FITS file is pixel #1, which would cause the CFA pattern to be incorrect.

Attached is a screenshot of the improperly debayered file in APP.
