I tried to generate a mesh from the "Heightmap" menu, and used the name "Euclid Mesh" which then threw an error that indicates the name is not being quoted properly:
Malformed command
'BED_MESH_CALIBRATE_ORIG PROFILE=Euclid Mesh'
'BED_MESH_CALIBRATE_ORIG PROFILE=Euclid Mesh'
When I rerun with a name that has no space, it works fine.
