When I'm viewing Estimates for a particular customer, a lot of times it's to be sure that we suggested and quoted for a product that would benefit them. In this case, it was a security suite and firewall unit. Assuming they declined it (because it was never sold), I clicked the SHOW DECLINED button and it just dropped me into a pool of all declined estimates instead of just those proposed to the client. The search filters included aren't useful for finding client-specific estimates.
