Abstract
Proposition 4.1(i) of [1] is incorrect, i.e. the sequence of Cesàro-sections ${σ_n x}$ of a sequence x in a translation invariant BK-space is not necessarily bounded. Theorem 4.2(ii) of [1] and the proof of Proposition 4.3 of [1] are corrected. All other statements of [1], including Proposition 4.3 itself, are correct.
