Language detecting problem

The first time I tried creating a quiz by detecting the language it translated everything goodly to my languege (slovak/slovakia) but later on with the premium version I also use detect languege but its all in english - the questions and the answers too. Sometimes the answers are half in english and half in my detected language which is really confusing. I want it to be detected to my language as it was at the start. I dont know the reason why it has changed.
