Is anyone having issues with Web Windows?

I am using Lectora 18 and there is several pages that have Web Windows on each page. When I review the pages in Lectora (Run Mode, Preview Mode, Preview in Browser), everything is working fine. When I publish and test in the LMS though, the Web Window does not show up at all. I have verified that the websites are correct and working. I even tried creating a new page but still have the same issue. We are trying to avoid having pop-up pages outside the training course. Any help is greatly appreciated.
