Merged Projects- PIX4D Matic, Drone & Catch Pro

This one has me stumped. I merged a PIX4D Catch Pro to a PIX4D Matic drone project. I used three MTP for the merge. The drone project has GCP’s. All that looks great after initial calibration of each project individually. Once merged, I can generate the depth point cloud, but it fails repeatedly on the Dense Point Cloud. I turned on/off the noise filtering, sky filter, and reduced matched from 3 to 2. Same result. Error says I have insufficient GPU, but GPU monitor says I’m only reaching 47% of GPU ability. Ultimately, I reduced the images from 1/2 to 1/4 and it processed as expected. Anyone know what’s going on here? Matic V2.10
