I am trying to update from V6.1 to V7, (I have a valid OPW contract) however there were many unresolved points and bugs related with address and partners issues.

my question is: Are there still bugs/unresolved points related to address/partners changes happened in V7 ?

Problems I encountered:
1. There are many empty customers without a name on the first page of the customer list view.
2. When selecting delivery address in sales order address related to other partners are also listed.
3. In accounting every address is like another company in reports and many calculations.
