When you go into the keyboard binds menu for pc, it says that you can delete keybinds by hovering over the bind and pressing either backspace or the delete key, but neither of these work

Yeah, it hasn't worked for about 6 or 7 years, although it used to. I think it may have been borked when the Interface got redone shortly after the initial Android port (may have even coincided with the Windows Store release). Basically, historically when you clicked on a command to select it, it didn't used to go into BIND mode like it does now, you used to have to second click it for that (The item selected used to go yellow for highlighted, then red when clicked again - so not a double click) which may have caused issues with touch control methods. I know when the initial Android port appeared you could also use the "back" button to unbind a key, but this was changed shortly after as it was easier for mobile users to just use 1 press. (The fact that you had to press a command twice confused some people or something)

Anyway, I know there are other threads about this, that the developers have responded to but I would not hold my breath for a fix. The only way to currently unbind a key, without opening config files is to use the /bind <KEY> NONE command (or /bind <KEY> "").

The keyboard/input menu needs a lot of work, besides this bug, and although it might seem like something that is "easy to fix" - nobody can make that assumption.

This is still an issue, devs. If you don't plan to fix it in the near future, could you at least edit the Help text to remove the non-functional directions and replace them with an explanation of how to clear bindings with /bind?
