Harvest Moon - Magical Melody: Problems with filling the watering can

[Bellis]

I hope it is ok, that I ask here, but in the GameCube section, I can't start a new topic.
I recently started the game and am having trouble filling my watering can. I've tried it at every fontain, but she still watering and no filling the can. Am I doing something wrong or is it a bug? Anyone with the same problems here?

I would be really grateful for help!
Best regards!
