Incorrect Times

I have imported the times in for the full year and some of them don’t seem to have worked. I then tried to re import it and it is now saying the times and dates are not the right format even though I was using the same csv I uploaded last time.

Also when I am on the settings of the plugin in WordPress it is so very slow that I have to wait a few minutes just to be able to click something.

Anyone else having these issues?

Thanks
