BOM not working properly

I have created a BoM for an Item named 60x30 1up Chromo High gumming with raw material as ROLL-105 AS KMH4644. And to get ROLL-105 AS KMH4644 i have an another bom with raw material as ROLL-210 AS KMH4644.

When I try to create a work order for 60x30 1up Chromo High gumming in raw material item table ROLL-210 AS KMH4644 this item is getting added instead of ROLL-105 AS KMH4644. How can I solve this?
