error _wpnonce used twice

A warning is being displayed at my site here:
http://ar.ditempi.com/mi-cuenta/

First I brought the issue to the authors of another plugin that seem to be conflicting with YITH’s. You can see that here:
https://github.com/mundschenk-at/wp-typography/issues/12

The answer they gave me was this:
The same ID (_wpnonce) is used for the nonce in both the registration and the login sections. This is a violation of the HTML specification. Although browsers are forgiving, DOM parsers are not.

The warning can safely be ignored, but you should report the error to the authors of YITH Woocommerce Social Login, they are the only ons who can fix it properly.
