How soon after the lime applications was the soil test done? I've seen that before. I would say that either the lawn has been excessively limed, or an app was done within a month of the soil test. As to how do you proceed? I wouldn;t do anything. Every time it (acid)rains the pH will go down. The high mag/ca content might gum up the works, tie some nutrients up, but shouldn't be anything major.
