i think its worth noting that when importing the parasolid to solidedge, some of the solid bodies for the hull are getting united. if it's possible to export the model with the assembly exploded, that should solve the problem.
check your setting, most cad packages have options to import assembled step files as assemblies of parts or multibody parts vs a single part
I tried various permutations of the import settings when importing in SolidEdge 2023 and it was yielding the same result. I should mention that importing to Bambu Studio has the issue between the same bodies in the hull as SolidEdge 2023. It does import cleanly into NX 2212.
