Tags - problem

[Marketer]

Hello,
I have a question about tags in multistore. I understand that we can use different tags for different languages, but I can not handled, how can I set different tags for different stores?
For now the same tags are displaying in different stores in my multistore. I thought that if I set tags for "product 1" in "store 1" it should display just in "store 1". But they are display also in "store 2".
This not look well. Do you have any suggestions about, how can I solved it?

Thank you in advance.
