Admin header message breaks site when WP language is set to spanish

So I switched the language on my local WP site running WP Reroute Email, and suddenly it’s totally broken.

I tried it on two different local sites. Both times I could trigger it like this:

– Install WP Reroute Email
– In Settings > General, change language to “Spanish”

What I see on most admin screens is that the whole content of the screen after the WP Reroute Email message becomes a giant link, and clicking anywhere on the site takes me to the WP Reroute Email settings screen.

Notably, switching to “Espanol Mexicano” fixes the problem, so I suspect it has to do with the particular translation file for the plain “Espanol”.
