Hola Shane

Thanks for letting us know. There's no error in the answer, it's still Me gustan because in the Spanish we have it in plural "los bailes irlandeses" which is the most common way to refer to "Irish dancing", in plural, as if saying "Irish dances". But we get this creates confusion because you see the singular form in the English and the plural form in the Spanish, so we made it all plural by changing it to "los bailes tradicionales" ( traditional dances ) 

I hope it helps.

Saludos cordiales
