Modify Display Filename and Layer on LCD Plug-In

[NotAce 0]

I want to modify the Modify Display Filename and Layer on LCD Plug-In so the total number of layers is displayed at the beginning of the line instead of the end. I tried the following:

• Opened DisplayFilenameAndLayerOnLCD.py  from the  C:\Program Files\Ultimaker Cura 4.4\plugins\PostProcessingPlugin\scripts folder into a text editor (after backing it up).
• Modified line 75 of the script to read    display_text = lcd_text + str(i) + "/" + max_layer + " " + name    (i.e. added    + "/" + max_layer)
• Saved the script.
• Restarted Cura and resliced my file.
• There was NO CHANGE to the generated GCode.
• So I shut down Cura and restarted my PC.
• Opened Cura and resliced the file.
• Still no change

There's obviously a magic ingredient missing here. Can anyone tell me what I'm doing wrong. 

Thanks.
