Carry Forward leave should be generated in PT60

Hello Friends,

I am doing Leave accrued for monthly basis but right now does not required carry forward leave should be generated though PT60.

Please check attached screen and let me know, where is rule 4 is mapped.

Because we have updated carry forward leave through LSMW and now I execute PT60. system creating 0 leave balance in the carry forward leave but it is correct generating 2.5 leave balance monthly credit.

Please help me out.

Thanks
