Pause command no longer working after installing Jyers UI

[Pugs7]

I just upgraded the firmware on my 3V2 to Jyers UI. Previously I had a lot of problems with an inconsistent Z position, so I inserted these commands at the end of my start-up routine that would cause the printer to pause and allow me to tweak the Z offset:
G90 ; Absolute Positioning
M25 ; Pause SD Card Print
G1 Z5 ; Lift Z axis
G1 X117 Y117 F3000 ; Move to Bed Center
G1 Z0
M25 ; Pause print

Jyers is not liking this command set. After printing the test lines along the left edge of the bed, the print head moves to the center of the print bed, then moves down to the bed, then up in Z, then to the left rear corner of the bed and pauses. Then I have to hit print to resume, and the screen then asks if I want to purge more filament.

If I remove the above command set from the file, it executes fine. If you have any idea what is going on, and how to resolve, I would really appreciate the help.
