I found a bug doing a half marathon plan with coach Amy... two weeks ago I participate of a race and I changed the day of my long run from sunday to next week sunday. I made the long run as I changed... but the sunday after (two weeks after my race) I had 2 long runs in my calendar... so I decided to change my long run’s to see if the second run could disappear ... all my schedule was messed out :( cry 
so I changed back my long run for sunday and the longrun from 2 weeks ago came back !!! This bug is annoying and I dunno what to do because I can’t delete this workout. Please any idea to fix it ? (Sorry my bad English, but there is no french forum)
