Why is there difference in the address Difficult to understand the loadJTOC offset and copyD2U()

EG  call                     AF CF OF PF ZF ESP = Addr 0x00015e08, static"< SystemAppCL, LDev; >.one ()V",

is the same call where the address changed after setAddress

ia32_call                AF CF OF PF ZF ESP = <0+1460232336>DW, static"< SystemAppCL, LDev; >.one ()V" ESP

Please Help
