Problems with mysql event and inerjoin not running

I am programming an event but it does not execute it, if it executes other events as simple updates, but when I put the inner join it just does not do it, it can be said that the inerjoin does it if I do it manually

for example this event if you do it

DELIMITER $$
CREATE EVENT regist
    ON SCHEDULE
      EVERY 1 MINUTE STARTS '2018-06-08 14:00:00'
    DO
    BEGIN
       update bd_tokens.superto set num_bug=1;
    END $$
DELIMITER ;

But making an inerjoin does not make changes
