Redirects malformed on setup

In a multisite setup, on a site with prefix /es/.

Enable redirections plugin across network.

Within /es/ site CMS, configure a redirect from location ‘lorem/ipsumes’ and save the redirect.

You’ll see the redirect from url got trimmed to ‘lorem/ipsum’, and similar behaviour can be seen for the url:

‘lorem/ipsumes/123es’ which becomes ‘lorem/ipsum123’

It looks like its replacing the sites prefix from my source url on save. I’ve managed to force the correct configuration for my redirect by updating the value directly in the database: but im pretty certain this should be fixed.
