Map check: "no components found to joint"

I have blueprints where I added and set up a physics constraint component manually, to be used later. Map check lists these actors in a series of warnings:

MyBP3 : No components found to joint.

Can I make this warning go away? I tried breaking the constraint right in the construction script but that didn’t help. (I found no other way to deactivate the constraint.)
I believe setting up the many constraint properties beforehand in a convenient details panel is a legitimate usecase.
