Garmin Connect not showing correct Average and Max Speed values

Hi,

I searched the forums and the known issues and cannot find a problem like mine. I have a Forerunner 305 that I use with Garmin Connect. When I go for a run the device itself records everything perfectly. For example, I did a run this evening and the device says I ran for 54 mins, ran 7.73 km, burned 542 cal, my average speed was 8.6 km/h and my max speed was 12.1 km/h. Import that run into Garmin Connect and the time, distance and calories are fine, BUT Garmin Connect calculates average speed as 7.00 km/h and max speed of 2.59 km/h, which is clearly totally impossible. Also, runs where I know I ran slower show up as though I ran faster, but only in Garmin Connect. The data in the device itself seems fine, and something seems to be going wrong when the data is transferred to Connect, or in display or calculation somewhere.

Anyone else seeing a similar thing? Can it be fixed? I don't care that much, as the data on the device is correct so I can view it there, but it is annoying! :)
