Delete log after X days

Hi, I set the expiration days of the log that creates your plugin in 45 days, through a php function you suggested to me.
But I have a problem, I have many rows in the tables created by your plugin. Why?
How can I only delete lines older than 45 days?

The php function that should clear the log older than 45 days is this:

add_filter( 'simple_history/db_purge_days_interval', function( $days ) {
	$days = 45;
	return $days;
} );
