Keybinds reset when switching versions

So recently I have noticed that every time I switch versions, my keybinds reset to default. It gets annoying to keep changing them each time I switch to a different version (example: 1.12.2 to 1.13.2). And I think most people also have a problem with this too. Please fix this so that when you set your keybinds once, they stay like that for every version unless you reset or change them.
