A bug maybe
I use Traditional Chinese version of Todoist, when click the button of "Recent 7 days"(7日), I got "(過期, 7 _天)" filled in the search box, which is incorrect, "7 _天" should be "7 天" ( removing the underline).
To confirm, when viewing the 7 Days view, the search bar has 7_Days instead of 7 Days. There is an underline where it's not needed?
I will let the developers know about this.
This should now be fixed. Thanks for your report!
