Widget stopped displaying in sidebar

Hi guys,

I’m pretty fresh in WP. I have problems with Alfie WP Weather on this site https://www.apartmanidi-bol.com/

Widget should be displayed in the first box in the sidebar. Sometimes it shows up, but most of the time it’s down. When I try to change some parameters in the sidebar it takes some time to apply, so maybe it’s the problem with the theme?

Please let me know what should I do.

Thank you!
