Remove all superelevation data

Hi,
I want to remove all superelevation data from an alignment. I tried it with Python script and with Civil3DToolkit nodes as well.
The behaviour of the python method is very strange. At the beginning it detects 12 critical stations, so It would be reasonable to remove all with a while loop one by one (always the one with 0 index). But it didn’t work for me. I could only delete some with manually (from index 1 to 5).
It would be very helpful if a “Clear all superelevation data” would exist.
Here are my test dwg and dyn files.
