Strange issue with the sidebar on my website

Hi everyone!

I recently started working for a company that is using a www.ads-software.com website. I have some background in using wordpress, so I felt somewhat confident about making simple changes. On our website there is a main column and a sidebar. The sidebar had redundant information in it, so I decided to move that particular widget to “inactive”. Doing so screwed up the whole sidebar. I put the widget back in, but the problem remains.

I am the marketing coordinator for this company and the web issues (the big ones anyway) are handled by an outside company. I would rather not get them involved if this is something that I can fix myself.

Here is the website: https://www.stlhealthyfamilies.org

Any ideas what may be causing that problem?

Thank you so much!
