Hello all!

Can someone help me to save my 2D transfer function?  
In the image below you can see that the button is not available.

What I did so far:

1. loading of vtk volume data
2. representation as volume
3. editing of color map
4. checkmark set at Edit 2D Transfer function

My paraview version is the latest: 5.11.1

My plan was to use Paraviews user interface for the design of the transferfunction and then export it to a vtk suitable format (For the use of my own vtk-Skript)
