ERROR: Duplicate names detected.

I tried to run the heat transfer case（https://mooseframework.inl.gov/modules/heat_transfer/tutorials/introduction/therm_step03a.html） in the moose tutorial, but an error occurred when visualizing it in paraview. The error is as follows:

ERROR: In ./VTK/IO/IOSS/vtkIOSSReader.cxx, line 934
vtkIOSSReader (0x63392d10a220): Error in UpdateTimeInformation:

ERROR: Duplicate names detected.
The name 'bottom' was found for both SideSet 0 and NodeSet 0.
Names must be unique over all types in a finite element model.

I tried to ask GPT, and he said that the names of node and side are repeated, but I don't know how to solve this problem. I want to ask if my system environment is configured incorrectly. I would like to ask everyone how to solve this problem. If someone can answer, I will be very grateful.

Hello

Newer versions of paraview won't error on this I think. This is because MOOSE always creates the nodeset associated with the sideset, and gives it the same name.
5.10 has this problem I think.
5.9 is fine

You can prevent moose from creating the nodeset by setting Mesh/construct_node_list_from_side_list = false
