Would you believe there is a lot of research evidence that most babies identify their fathers with play and their mothers with more traditional nurturing activities?
As gender roles in families change, with concerned fathers now providing more basic care than used to be the case, that pattern may disappear. Unless it seriously disrupts the family schedule, I wouldn't try to change anything. Her preference pattern gives both of you a special role—and an opportunity for an occasional breather. Her primary attachment is undoubtedly to you, which is why she needs you when she wants comfort. She will, in time, become more interested in playing with you, too.
