ZFC separation of properties $(\kappa_2)$ or $(\kappa)$ from weak $\lambda$-spaces

Construct in ZFC a space $X$ with property $(\kappa_2)$ or property $(\kappa)$ that is not a weak $\lambda$-space.

Background

The paper establishes that every weak λ\lambda-space has property (κ2)(\kappa_2), and it also recalls that property (κ)(\kappa) implies property (κ2)(\kappa_2). Under Martin's Axiom, it gives a space with property (κ)(\kappa) that is not a weak λ\lambda-set, but this does not provide a ZFC example and concerns the set version of the terminology.

Question 3 asks whether the separation can be realized in ZFC: specifically, whether a space satisfying the stronger combinatorial property (κ)(\kappa), or at least property (κ2)(\kappa_2), can fail to be a weak λ\lambda-space.
