Problems cutting a solid created in Dynamo


I’ve been working in a project where I have a section view. In that section view are represented different solids, all as generic models, all created in Dynamo. The cut pattern presentation is not good, as one solid behaviour is different than the others (see image). All the objects have the same category (generic models) and the same material (concrete). Is this a limitation of solids created in Dynamo ? Can anyone help me please?
