KLEO Posts not working

Dear KLEO team

I have my home page designed with rows of individual posts, I created that using KLEO Posts element with Visual Composer. But this is not working anymore.

WHEN I go to: add element–KLEO Posts—KLEO Posts settings—Build query—-Individual Posts/Pages/Custom Post Types—-and I input the title of the post in order the element to find my desired post THEN it doesn’t work.

The KLEO Posts element gets freeze and eternally “thinking” without showing any post and post names don’t appear. And it is the cause that I couldn’t select any other post and fix it. So I can’t publish more posts on my home page.

I’ve tried to update KLEO theme and visual composer but it doesn’t work, maybe I missed something?

I send you an attached image in order you to see what I’m talking about.

Thanks
