Removing additional options from vex editor in Houdini?

[archz2 1]

In Houdini versions earlier than 19.5, the vex editor for attrib wrangle looks like this. 

 

 

But in Houdini 19.5, it looks like this with additional options in the bottom left as a drop down menu. 

 

 

Automatically, it switches to Hexscript mode and messes up the code by adding additional inverted commas in the beginning and end of the code. 

 

Any way to avoid it?
