unable to load binds if certain keys are bound

[joeyjumper94]

Describe the bug
using keys that have a - in their name will save to the config, but will be treated as not bound when the config is loaded

To Reproduce
start minecraft and go into a world.
open chat and type ".bind ClickGui grave-accent"
you should now be able to open the GUI with "~"
shut down minecraft.
relaunch minecraft and go back into a world.
you can no longer open the GUI by pressing "~"

Expected behavior
after relaunching minecraft, Kami should still remember what binds i set

Environment
kami build was downloaded from the december 1.16.4 build https://github.com/zeroeightysix/KAMI/releases/tag/1.16.4-dec
Windows 10, 64 bit
Java(TM) SE Runtime Environment (build 1.8.0_261-b12)
Additional context
when i look at the config file after trying to set a bind, it is indeed saving
some excerpts from the file after saving when i had just set the binds
"Bind": "key.keyboard.f", F on my keyboard toggle brightness module on/off
"Bind": "key.keyboard.grave.accent" grave-accent or ~ on my keyboard open the clickgui
"Bind": "key.keyboard.right.shift", right-shift on my keyboard, toggle killaura
some excerpts from the config file after saving when loading it
"Bind": "key.keyboard.f", F on my keyboard toggle brightness module on/off
"Bind": "key.keyboard.unknown" bind for clickgui is forgotten
"Bind": "key.keyboard.unknown" bind for killaura is also forgotten

it seems like other clients have the same issue with this key ~ something about it seems to cause issues
