Shift + Numpad 5 combination is hardcoded and can not be reused

What is interesting is that whatever you setup as shortcode, in premiere, for Shift+Num keys (3-9) does the same thing.
Like I've said, it's not autohotkey problem, with it off, same behavior.
The following is mapped for me in Premiere for Shift+Num5 and Num8, it does not perform this action.
No issues with Alt or Ctrl Numpad mappings in premiere.

The problem lies elsewhere (prob. windows system), I mentioned Autohotkey because it is interesting that it gets over-rulled.

My understanding is that the way Autohotkey works, is that it intercepts the key combinations and performs the required code. Mapping of Shift+Num5 for example should perform a different premiere combo I set up that helps me edit.
The combo is never fired I tried different workarounds.

+numpad5::
if WinActive("ahk_exe Adobe Premiere Pro.exe"){
    sleep 1000		; whatever else overrides me
					; waiting 1s would allow my further behaviour
	send {Esc}		; normally even if timecode is selected
					; sending esc would take me back to timeline
					
	send +{down} ;my actual desired action
}else {
    send +{5}
}
return 

I just experimented without the Premiere wrap to enable map on all the system and the combinations don't work as expected.
I believe the conclusion is that this is simply a Windows environment problem.

+numpad5::
    sleep 1000		; whatever else overrides me
					; waiting 1s would allow my further behaviour
	send {Esc}		; normally even if timecode is selected
					; sending esc would take me back to timeline
	send +{down} ;my actual desired action
return 

+numpad8::
    sleep 1000		; whatever else overrides me
					; waiting 1s would allow my further behaviour
	send {Esc}		; normally even if timecode is selected
					; sending esc would take me back to timeline
	send +{up} ;my actual desired action
return 

Further internet scan shows that other people have issues with shift+Num keys in windows on various atempts to do other things.
On future Premiere updates, Disabling the Shift+Num keys on Premiere keyboard mapper would hint people that it would be an invalid choice (Windows environment wise).
