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.
