Unimarc sample data : items' itype are not imported

Unimarc sample data items (/data/sql/unimarc/1812/after_22155/items.sql) have itypes that do not match the itypes codes existing in Koha, so they are not imported when you create and sandbox. It breaks the Opac details page (see BZ 32747) so if you don't know about it you cannot test a Unimarc patch on the Opac. I opened a bug on bugzilla (BZ 35896), I was told it comes from this project. Is opening an issue here the right thing to do?
