Widget don’t sort in right way

I’ve double checked and this works fine for us https://demo.yendif.com/wordpress/

Kindly share me your site link in where I can see the issue.

Hello,
I have checked your Code and it is correct.
Don’t know why it doesn’t work.
But I changed the wordpress-loop to an php-foreach and so it works now:

Maybe you don’t recocnize your Plugin, I modified it a little bit ??

Thanks for your Help
