Odoo9 Contact Filter Problem with Tags and root category
I have a big problem with the tags filtering on contact.
A lot of contacts have many tags. For example the contact1 has a tag called invited. The root category of "invited" is no1.
Now when I search the tag "invited" Odoo is showing me all contacts with all "invited" tags included them with an other root category.
When I try to filter no1 / invited , this is not working.
How Can I make a clear filtering with the root category on each tags?
