[Koha] Import Unimarc records with items

Hello! There are records with items in UNIMARC format. Records are imported. Items are not imported. Why is this happening? Are there other options for importing items? Example: ... <datafield tag="995" ind1=" " ind2=" "> <subfield code="5">2001-01-01</subfield> <subfield code="9">1</subfield> <subfield code="a">NF</subfield> <subfield code="b">TPU</subfield> <subfield code="c">TPU</subfield> <subfield code="f">13821000185704</subfield> <subfield code="j">95-1389</subfield> <subfield code="k">95-1389</subfield> <subfield code="q">3700,00</subfield> <subfield code="r">BK</subfield> </datafield> ... Good Luck!
