Add missing spaces to option labels

Quick PR to add missing spaces to some of the form labels. It looks like some were accidentally removed in #165.

Could it be better to provide context to the translators with the use of _x() instead of __() and the code comment for translators? It seems like _x() was created for that: https://developer.wordpress.org/reference/functions/_x/

Yeah, _x() may work better for all these translations. Maybe it would be better to update all translations using this function in a separate PR?
