Help!: [Sink] MMR isn't seeing all workouts/maps for the month

I'm new to MMR so my problem might not be that big of a deal but someone has probably had  this problems in the past and can help me out.

 I have a Garmin 305 Edge and I'm trying to download this months workouts but any workout that I did in the beginning of the month aren't being downloaded. I'm not sure but I think this is because of the way the Garmin saves workout by the week.In other words the 2nd of August falls on the same date as the the 31st of July.Is this the problem or is it something else that I'm missing?

TIA

Kyle
