How to disable regex while importing csv

I have a csv with redirects. If I import it, the regex is set to all the links.
I’ve tried several formats, but every time the regex is set:

https://domain.com/oldlink1/ – https://domain.com/newlink1/
/domain.com/oldlink1/ – https://domain.com/newlink1/
domain.com/oldlink1 – https://domain.com/newlink1
etc.

Can someone tell me how to disable this when I import a csv? I have a lot of links an manual import is no option.
