Backspace removes extra space after installing delimitMate

Question

I want Backspace key to remove only one space all the time, but after installing delimitMate, it removes extra space. Let's say I want to type the code below.

let hello = "some text";

While I'm typing this, I accidentally type extra space after hello, so there are two spaces between hello and my cursor as follows.

let hello  |

And, at this point, I decide to remove one space with Backspace, but it removes two spaces instead, so the cursor ends up next to o as in hello as follows.

let hello|

Now, I have to type space again to make sure there is one space between hello and =. This is redundant and I don't like this. Does anyone know how to make Backspace remove only one space all the time with delimitMate installed?

Edit:

Thanks to the comment from B Layer, I found the mapping that was causing this. After commenting out the mapping code, I was able to remove only one space with Backspace key, but now when I delete a matching pair, it only deletes the opening one, and the closing one stays intact.

Before

After

The creator of delimitMate gave me a solution that worked for me. I'm a Rust programmer and this solution is specific for Rust files, so I don't know how this works for other files.

Add au FileType rust set sts=0 to your neovim config file.

Now, when you press the backspace key, it only removes one space. Take a look at the issue I opened at github for details, which led me to this solution.
