Sort and translation problems

Hi,

I am using the “404 to 301” plugin version 3.0.7 and I am facing several problems.
The first two problems are related to sorting.
The third one is related to translation.

1) the 404 error entries are not sorted by default (see screeshot at https://www.dropbox.com/s/p1kubvuegljg4al/404%20to%20301%20problems.jpg, circled in red);
2) sorting is not possible by clicking on column headers;
3) French translation is incorrect: the right translation is “Supprimer” and not “Suppirmer” (circled in blue).

Best regards
