Typos when instructions are translated to spanish

Hello,

We are using this plugin in our web site, it is configured to use spanish as the main language so when selecting a content type from the list all the instructions are displayed in spanish.

I have found a couple of typos for Fill in the blanks content type, for example, Score range is translated as "Tango de Puntaje" instead of "Rango de Puntaje" or in the behavior configuration, the option Require all the fields to be answered is translated as "Requerir qye todos" instead of "Requerir que todos".

Is there a way to fix this in the plugin? or is this a problem on the way Wordpress is doing the translation?

Regards,
