Hi,
you didn't need this IP for your custom board.
Actually, he should no longer see it once you have removed it. Maybe your block design is corrupted and there are still some information about this IP available (this can happens sometimes, you didn't see it in the gui but there are older information left) --> export this design as TCL and check content open the block design xml file. In case this isn't the reason, remove this IP from the local repository, so that it's completely unknown for Vivado.
PS: When you use starterkit design on your own carrier, check all MIO connection. PS setup was repaired for starterkit (means TE0808 with TEBF0808).
