Copy blueprint

Steps to reproduce:
1. Import provided blueprint
2. Place blueprint in inventory
3. Edit blueprint: delete the constant combinator by RMB (dummy entity to 'burn' the first and second ingredient of parameter)
4. Save blueprint
5. Place blueprint in world and set the parameter

What happens:
The two assemblers on the side take the first ingredient of the parameterized recipe.

What I expected:
The two assemblers still take the third ingredient of the parameterized recipe, as they do when step 3 above is skipped.

Why this is a bug:
When the following steps are followed the behaviour of the blueprint does not change when the dummy constant combinator is removed.

1. Import provided blueprint
2. Place blueprint in blueprint library!
3. Edit blueprint: delete the constant combinator by RMB (dummy entity to 'burn' the first and second ingredient of parameter)
4. Save blueprint
5. Place blueprint in world and set the parameter

Extra info:
happens with recipe item and numerical parameters.
both blueprint libraries work "correctly" ("game" and "my")
tappi (veltik) in the Discord confirmed that the bug also occurs in version 2.0.25

Also, it would be nice if there was a button in the UI to add a new parameter, so that placing dummy entities is not needed, and for "ingredient of: <parameter> #x" to have a formula field for x.
