superconductivity - quark momentum and quark mass in unpairing and pairing phase


In this Review paper in p.1464, top left: Rev.Mod.Phys.80:1455-1515,2008 -- Color superconductivity in dense quark matter


It shows a figure of quark momentum of quark $u,d,s$, in unpairing and pairing phase, such that


$$p_d >p_u>p_s$$


however, we know: $$ m_u


so why isnt that $$p_u >p_d>p_s$$ if momentum is inverse proportional to the quark mass? What is going on here for these quark momentum?
