Create training, save - minutes deleted

Hi,

in preparation für the training-week I create my trainings with Garmin Connect Web (on my MAC Airbook) and send them to my Garmin 1030 - for years, successfully, thanks!

No there is a problem, let´s say for 1 week:

- I name and create the training, e.g. ten blocks à 10 minutes.

- I save the training - and the minutes are partly deleted and set to "0".

- I refill the minutes, again some of them are deleted and set to "0".

- Sometimes I have to repeat these steps for 5 and more times, before I can save the training with the inserts minutes ...

Who knows the problem - and who can give me a hint to solve it?

Thanks in advance,

Martin (Germany)
