Creating Timeslots not working

Was just trying to add timeslots through ult/fields/timeslots/create. I get the following warnings and it states that the 2 timeslots could not be created due to overlap. However, the 2 timeslots are created but the field isn't assigned and it's not visible when you go to "view timeslots".

I've included a screenshot which you can see at http://kelownaultimate.com/kups-fields-error.png

2 timeslots could not be created, due to conflicts/overlap with already existing timeslots.
