I tried to open a Bohr-cml file in paraview. First time it showed the structure however agin second time when I opened it, it was showing only background

I’m not able to reproduce here. With ParaView 5.13:

- File / open, choose a .cml file, apply
- do it again
- → both show properly

Can you share some data? Can you detail yout steps please?

ParaView 5.6.2 is pretty old now. The latest is 5.13: [https://www.paraview.org/download/?version=v5.13](https://www.paraview.org/download/?version=v5.13)

Can you retry with it ?

Thank you so much for your help. I have made it enabled by resetting it.
