double columnName in MAT295 - keyword for anisotropic properties - write issues #995
Description

- I am using a Python virtual environment
🐞 Description of the bug
i'am trying to write a kyword-file containing MAT295 Keyword with anisotropy modelled via HGO-Model with two fiber families.
Unfortunately, there seems to be an issue while exporting the GroupTable: "ValueError: Cannot set a DataFrame with multiple columns to the single column ftype"
Within the dataFrame there are two columns with the name ftype.
quick workaround by renaming the column:
mat295.anisotropic_settings.columns.values[7] = 'ftype2'
This solves the issue for wrting, but two lines with the stiffness are still missing!
