Month View – Navigation Links

Hello

I’m not able to show the next month link and the previous month link in the month view.
Only avaliable if I search something, but on default view in month/nav.php the functions: tribe_events_the_previous_month_link() and tribe_events_the_next_month_link() always returns an empty value

Any help?
