Tartarus V2 Pro: Reassigned Hypershift button still dims lighting (Turns off all keys except 19) - Bug?

Hi everyone,

I am having an issue with the dedicated Hypershift button on my Razer Tartarus V2 Pro. I decided to reassign this button to be my "Space" key instead of Hypershift.

The key mapping works, but every time I press it, it still triggers the hardcoded Hypershift lighting effect: it turns off the RGB on all my keys except key "19". The actual Hypershift secondary functions do not trigger (which is correct since I reassigned it), but the lighting still behaves as if I am pressing a Hypershift modifier.

Because I am using this button as "Space", it is very distracting to have my entire device go dark every time I press it.

My questions are:

  1. Is this a known bug in Synapse for the Tartarus V2 Pro? (The lighting shouldn't trigger if the button is no longer assigned to Hypershift).

  2. Is there any workaround to stop this button from turning off the lights, so I can use it normally as a Spacebar?

Thanks in advance for the help!
