I created a new entity. In this entity i'm created a two lookup field to keep contact in them. Then i'm create relationship 1-to-many, and based on this connection created subgrid.

In this contact in subgrid you can see some record, but when i go to the contact "test2 test2" ( in the screen below ), i'm didn't see this record.

What i need to do to see the record in subgrid in two contacts?
