Similar redirects to different domains do not work

[SeBigBoss]

I've a multi-domain setup.
I want to set similar old URLs at different domains redirected to different target URLs.
This doesn't work as the extension changes the old URLs.
Example:
Redirect from
/oldurl/ > www.abcdomain/somethingnew/
/oldurl/ > www.xyzdomain/somethingelse/

This causes a change to
/oldurl/0 > www.xyzdomain/somethingelse/ ... so only the redirect for the first Domain works.

I do not enter the whole domain, I select it in the Domain-Dropdown.
