Menu-items are placed in the 'Unpublished' queue.

-- HikaShop version -- : 6.4.1
-- Joomla version -- : 6.1.0
-- PHP version -- : 8.4.20
-- Browser(s) name and version -- : firefox
-- Error-message(debug-mod must be tuned on) -- : None

Menu-items are placed in the 'Unpublished' queue after changing # of columns to 3 in Products Options.

After that, it is not possible to mark the menu-item as published.

Any suggestions what could cause this situation?
