SLAM Troubleshooting

I have a SLAM dataset processing all the way through Rock Desktop 1.13.5 but I receive an error (screenshot attached) when attempting to align to world.

Once fully processed w/o alignment the elevations are off by 3-5 feet per gcp. This is what I was getting for elevation errors last fall until a Rock Desktop upgrade in January to 1.11.9 and I had five successful SLAM datasets.

The Rock R3Pro V1 has been upgraded to the latest firmware R3-PRO_SERVICE_V2.00.03_20240407 before this SLAM session.

Please advise
