Sorry, my question does not come across well.
I'll try again:
I have some addresses in My Places, the addresses are good.
To make it more clear, I would like to add the name of the addressee. E.g. Grandma.
When I do this, the tomtom suddenly shows a different house number on the address I entered earlier, I don't understand why.
