TBI PHY reg read of DTSEC2, DTSEC3 always returns 0xffff

we are working on P2040. we are unable to access TBI PHY register of DTSEC2, DTSEC3. read access to registers always returns 0xffff. access to TBI PHY registers of DTSEC1 is working fine. We have assigned unique/different PHY address to each TBI PHY of DSEC1, DTSEC2,DTSEC3

can any one tell why this is happening and the solution of this?
