Probably a Zebra/UNIMARC configuration issue. (The harder ones..)
Did you already try a complete rebuild btw ? Contact another UNIMARC user and compare zebra settings ? Or compare settings with the situation before the last update? Check your zebra logs, zebra-error zebra-output. Maybe you must enable some flags in koha-conf to get more verbose output. Follow the queries and look at the fields used in these 'unreadable' @attr 1=xx form etc. Verify that these fields are in the corresponding bib1.att under etc/koha/zebradb ..
