Dibi setSortableCallback multisort called only for one sorted col

Hello
I use setSortableCallback on more columns, but only setSortableCallback was called.
Grid show sort on more columns but, only is present in ORDER BY

$grid->setMultiSortEnabled(true);

$grid->setDefaultSort([
			'ROK'=> 'ASC',
			'MESIC' => 'ASC',
			'IDPODNIK' => 'ASC',
			'IDZAVOD' => 'ASC',
			'IDLS' => 'ASC',
			'IDLU' => 'ASC'
			], true);

$grid->addColumnText('IDLS','LS')
		->setSortable(true)
		->setSortableCallback(function(Fluent $fluent, $sort){
			$fluent->orderBy(sprintf ('gls.LS %s', isset($sort['IDLS']) ? $sort['IDLS'] : 'ASC'));
})

$grid->addColumnText('IDLU','LU')
		->setSortable(true)
		->setSortableCallback(function(Fluent $fluent, $sort){
			$fluent->orderBy(sprintf ('glu.LU %s', isset($sort['IDLU']) ? $sort['IDLU'] : 'ASC'));
})

I use datagrid version 5.7.1.

Can you help me please ?

Thanks

Start by reproducing the issue through setMultiSortEnabled(true), setDefaultSort(), and the two setSortableCallback handlers using datagrid 5.7.1. Trace how multisort values are passed to each callback and how orderBy clauses are assembled; done means all selected columns appear in the generated ORDER BY in the expected order.
