Hello @ricardopmarinho and @Kal_Lam ,
I also had the same problem concerning choice lists. I tested the problem in a simple form and it looks like the filter works fine throught the repeat groups. However, if I put a relevant in the select_one that has a filter, this field can not be used anymore. I uploaded here two simple forms if you want to take a look. The Form_test_with_relevant.xlsx contains the relevant and has the problem I said, and the Form_test_without_relevant.xlsx works properly.
