Not so much as a bug, rather a feature isn’t working properly. Validation, if I want a field validated as a URL, but choose to leave it blank, it won’t allow it. I don’t want the field required, but I do want it to be a URL should it be filled in.

I may be confusing, let me try again. If I want a field validated, but not required, that is not possible at this time. If I choose validation, but not required, it still requires it.
