I used 30 lingots to purchase the idioms in Spanish and the button changed to " take off". When I push that it changes to wear" , but the actual lessons don't appear. Any help would be appreciated.
Are you using the web site or the iOS app?
It sounds as if it thinks you have bought the Champagne tracksuit (30 lingots). The Bonus skills cost 25 lingots and just say equiped when baught. The tracksuit, which is only available on the app, is more likely to say take off and wear.
If you are sure you bought the bonus skill then report it to Support, otherwise it seems you're the proud owner of a flashy tracksuit for your owl.
