How to I change the M600 command generated by Sovol Cura without editing gcode every time?

In regular Cura, with a filament change script added, the M600 line reads:  
M600 E30.00 U300.00 X0.00 Y0.00 ; Generated by FilamentChange plugin  
in Sovol Cura it reads:  
M600 E30.00 L300.00 X0.00 Y0.00 ; Generated by FilamentChange plugin

That L300.00 generates a purge of 300mm after new filament load!

I can’t find a setting to automatically change the purge.

UPDATE:  
Never mind, figured it out.  
The line in the script called: ‘Later Retraction Distance’, should be labeled ‘New Filament Purge Length’.

Unless they meant that’s how much is retracted from the spool ; -)
