Day of week condition does not work

Hi all,

First of all, thanks for plugin it’s amazing!

I have a problem with the days condition.
When I click on it and enter some days in the field (ex. monday or saturday), I can’t save my rule so currently, I’m not able to make it work.

I don’t have any message nowhere however when I click on save or save and close, nothing happens.

Thanks a lot for your help!
