Qumran Sectarian Manuscripts is giving similar behaviour. It opens the first link and then it does not move when other links are selected.
I can't recreate this problem. Can you attach a screenshot to show an example of a link you are clicking on?
I do not own the Quaram resources but Legend of the Jews only goes to the home page.
I'm not sure this is the same issue, but I have a problem with https://ref.ly/logos4/Factbook?ref=bk.%23Satan, Cultural Concepts. Under Legends of the Jews, the popup on hover (here "The Journey to Moriah") shows the title page, not a preview of the correct content. Clicking on the link doesn't navigate correctly.
Thanks. I'm able to see the problem now. It's just for items in one of the groups that has a cover image. I've created a case.
