OXGCSEFR16 AQA GCSE french 9-1 'les lunettes'

hi, so i am having an issue, whilst using the AQA GCSE course by Luftschloss, when the word ‘les lunette’ comes up it goes into a loop repeating the word for me to spell out. this has happened on four separate occasions now with this same word, each time i reloaded the page. what should i do ?
