Plotting nodal displacement results in one node being selected after the plot, but only when using CINT for crack calculation.

🤓 Before submitting the issue
- I have visited the Troubleshooting section.
- I have searched among the existing issues.
- I am using a Python virtual environment.
- I am using the latest version of PyMAPDL and its dependencies (fully updated virtual environment). You can update them using
pip install --upgrade --upgrade-strategy eager ansys-mapdl-corein your activated virtual environment.
🔍 Description of the bug
The number of nodes selected after a plot_nodal_displacement("Y) is 1 if a crack is being used for crack calculation.
