Order image issue in a Image Browser gallery

Hi,
I have a problem with one of my galeries. I need to re-order some images in the “Image Browser” gallery Laurence Henry (https://galeries.photo-contraste.com/wp-admin/admin.php?page=galleries_bwg&task=edit&current_id=89). In the preview page, the order is the right one, but one my page (https://galeries.photo-contraste.com/laurence-henry/) the order of the images stay the wrong one. I’ve deleted the gallery, I’ve re imported the files, I’ve reimported the photo gallery in the page, acualize the page, … but it’s still the old order ! Any idea ?
Thank you for your help.
Kind regards,
Florence
