Hi,

I am using a UR5e, sw-verison 5.10 both on a simulator and a real robot.

When commenting out a screwdriving node and then commenting it back in using the button shown i the picture a new until node is created.

The new until node is an until success node and can therefore not be deleted.

This occurs both with my own impementation of a screwdriver aswell as the standard screwdriving installation.

Thank you for bringing this up!  
The behavior could be replicated and a Bug report was created.
