External links turned into site links

There are two links on this page https://www.meissnernordic.org/news/urgent-advoacy-needed-for-continued-funding-of-our-recreation-trails-program/ that are external links, but when you click on them you are instead routed to the current site. If you hover over them, you’ll see the local site “fill in” its URL. But external links elsewhere on the post are fine.

They are the Jeff Merkley and Ron Wyden links. All I can think of is that those links contain the same name as a page on the current site. Is there an auto fill feature I need to turn off?
