macos – Karabiner parts: ctrl + any_key not working

Im having the difficulty on Karabiner Parts the place key-bindings utilizing the ctrl key do not work, like reported by different customers https://github.com/pqrs-org/Karabiner-Parts/points/4354. I am attempting to make use of this complicated workflow: CTRL + h j okay l for arrow key motion however its not working for me, as an alternative ctrl + h deletes the character to the left of the cursor as specified within the keyboard shortcuts documentation (and idk learn how to disable that). My keyboard is a Logitech G710+ btw.

I am on the most recent model of Karabiner (16.0.0) and macOS (26.4.1).

My easy modifications positively work, and Karabiner Occasion viewer appears to be like wonderful. It recieves after I do left_control h j okay l: {"key code": "j"}, flags left_control.
