[Pause at layer resume failed]

I finally decided to upgrade from trusty Cura 4.8 to 4.10. I don't remember having to reconnect all my Octoprint printers with previous upgrades but I managed it.

 

I have a model that I want to do a filament change on and decided to try the pause at layer height (Extensions - Post Processing - Modify G-Code). The print was looking great and I was quite happy when the printer paused allowing me to change the filament. I couldn't find a resume option on the LCD but I did notice the Cura Monitor was showing the print was paused. So far so good right?

 

When I selected resume in Cura the print head crashed into the print. It was making so much noise I was busy aborting the print before something got broken and didn't notice what the LCD display said. It was almost as if the Z axis went to zero on the way to resuming the print.

 

Here's the settings for the Pause at Height script:

Did I forget anything? Any ideas if I did something wrong or is just not supported with my configuration?
