In Project settings, I cannot unset Allowed Domains

In my project settings, is there anyway to unset Allowed Domains? While configuring it, in an effort to block errors occurring during development, I set the allowed domains. However, we later found a different path, and used the configuration options in javascript. So I went into my project setting and deleted my allowed domains - however, this now caused nothing to be accepted from anywhere!

Is there anyway to unset these? Setting allowed domains ended up not allowing some development scenarios that we wanted to have. (especially trying to recreate the errors that we saw client side in development, and seeing if we could come up with a good reproduction).

You can use * as the wildcard to allow anything.
