Also, check your list ordering so lacing works as expected - the indexing needs to align. So “TABLAS” and lineweight 1 will update the import instance at index 0 in your List Create node (all indexes @ 0 get matched, followed by 1 and so-on). If its not working, its likely to be caused by a mismatching between your list order, i.e. TABLAS is a layer in the second import instance (index 1 of your list) not the first (index 0).
