Focal height setting is actually based on a few rules - since that looks defocused, it’s possible that when the auto-focus was taken, the beam fell off into a cut in the material and you wound up with a wonky setting for material thickness.
I’ll post the rules below, but the safest way to make absolutely sure that the beam is being focused in the same place is to enter the Focus Height value individually into each operation in the left thumbnail column. (Not in the Unknown Material height at the top.) The individual Focus Height will always be respected.
