Columns not working

I have a brand new Joomla v4 installation, and a brand new subscription to SIGE Pro.

THIS page is wher I am testing SIGE:
nj4.steamboat3d.com/index.php/photo

the SIGE directive syntax on this page is:
{gallery}myphotos/texture,column_quantity=3,turbo=1,limit=0,width=180,height=180,gap_h=9,gap_v=9{/gallery}

I have tried changing the plugin parameters in the plugin Gallery tab, nothing that I have tried makes the columns work.
PLEASE tell me what I m doing wrong ?

Thanks !
Kent
