Problem using "Set Certain Categories to Display in Homepage" with Polylang

I work with Clean Magazine Free Theme. I was using Set Certain Categories to Display in Homepage/Frontpage in “Appearance => Customize => Theme Options => Homepage/Frontpage Options” and it was working correctly. Now I had installed Polylang and introduced the translations of the categories in the different languages and when I intent to change Categories to Display in Homepage/Frontpage appear a message like “It seems that something has wrong. Wait a couple of seconds and try again.” I tried several times and the message always appears. Message appear so if I try to select all the categories, as if I select one, as if I select several. Do you know which problem may be?
