Custom Category Post Order Not working

Just installed this and it does not seem to work. Trying to reorder posts of the category ‘Travel.’

I’ve checked the category carefully, and loaded it several times. The order refuses to budge.
Just updated WordPress to the latest version.
Thanks for any help.
