Erratum to: Strong extensions for q-summing operators acting in p-convex Banach function spaces for 1 <= p <= q

[EN] Let X be a saturated Banach function space and denote by X' its Kothe dual. In the paper (Delgado and Sanchez Perez in Positivity 20: 999-1014, 2016) referenced in the title it is implicitly used that the closed unit ball B-X' of X' is compact for the topology s(X', X) on X' defined by the elements of X. This fact could be not true in general if X is not sigma-order continuous.
