Hi bas,
1.) This is a problem of using too small of a monitor. 🙂 On the page you see that on, at the top, click “Screen Options” and remove the fields you don’t ever use. This is more of a WordPress thing, rather than a WC Vendors issue.
2.) Try re-saving your Permalinks and see if that helps. ( https://www.wcvendors.com/knowledgebase/setting-permalinks/ )
Cheers
