Keybind Shift + Numkeys problem

[Messenger]

Hi,

I'm not sure if my title is clear enough but I seem to have an issue with my Numkeys Keybind setup. Currently my movement/camera controls are keybind on numkeys and my setup are these:

Numkey 8,4,2,6 = Character move forward, left, back, right
Numkey 7,1 = Character Auto-run, Character toggle walk/run
Numkey 9,3 = Camera Zoom-in, Camera Zoom-out

Amd some of my Job skill/abilities are set on shift + numbers (keys below functions), Now while my character is running and I press the shift button, my character will stop moving and even letting go the shift key will not resume my character's movement unless I press the numkeys movement again.

I tried to see If this problem can be resolved by removing all shiftkey-keybinds under all categories of keybind setting (Movement, Targeting, Shortcut, Chat, System, Hotbar) yet the problem still remains.

While removing all the shiftkey-keybinds, I notice that the shiftkey + numkey shortcut execute a following actions:

Shiftkey + numkey 7 - Open Hud Layout Mode (Current keybind setting: Home)
Shiftkey + numkey 8,2,4,6 - Move Cursor up, down, left, right (Current keybind settings: Arrow up,down,left,right)
Shiftkey + numkey 1 - Return Camera to Saved Position (Current keybind setting: End)
Shiftkey + numkey 9,3 - Cycle through hotbars up,down (Current keybind settings: Page up, Page down)

So I thought if I removed my current keybind settings on those affected/linked actions, the issue might get resolve but still no luck.

Would this be a possible issue or is this some kind of internal default/hidden keybind actions that cannot be removed?

Please help address this.

Thank you.
