Why same impact result in different scenarios?

Question

I am trying to model 2 different scenario of the life cycle of a building. I use OpenLCA 1.11 version and EF database.

First scenario represents the demolish and waste landfilling whereas in the second scenario,  the materials are recycled and used in another process as an input.

OpenLCA software gives me same environmental impacts for both of the scenarios. Does anybody have any idea why this would happen ?

Thanks in advance.
