Redirects to wrong URL

Hi, first post, please go easy on me!

I’ve got a wordpress site hosted on Bluehost (https://sydenhambroadcastingcoop.com)

When I click on any pagelink on the site (e.g. https://sydenhambroadcastingcoop.com/uplayer) for some reason it ALWAYS redirects to a longer version of the URL (e.g. https://sydenhambroadcastingcoop.com/the-sydenham-broadcasting-corporation/uplayer)

The page displays correctly, but the extra long URL is annoying, and it’s bugging me that I can’t fix.

I recently moved domain (from https://sydenhambroadcastingcooperation.com to https://sydenhambroadcastingcoop.com) but don’t see why that would have anything to do with it (but can’t recall if it was an issue before).

Any ideas? Help greatly appreciated,
thanks,
Merk
