What did you do?
1) Created a simple parameterised blueprint of a single constant combinator with a single parameterised circuit value: 2) Placed the blueprint, selecting Iron ore melting as the parameter value.
What happened?
The constant combinator is placed with a circuit value of Molten iron instead of Iron ore melting:
What did you expect to happen instead? It might be obvious to you, but do it anyway!
It should have the value of Iron ore melting instead, as pictured (by setting it manually): This would be consistent with the result when selecting Molten iron from lava .. which creates the combinator with a circuit value of Molten iron from lava: Does it happen always, once, or sometimes?
Always.
This also applies when selecting Copper ore melting. It will result in molten copper instead


Currently it's not possible to correctly assign the Iron Ore Melting recipe when placing a parameterised blueprint to a constant combinator.

Quick check suggests that this issue is already fixed for 2.1 due to change of recipe internal names (molten-iron -> iron-ore-melting; molten-copper -> copper-ore-melting).
