[Koha] Label Crator - problem with long lines

Hi all, I tried to print label for books with a text which was longer than one line. I saw that the Laber creator cut the text. Moreover, it cut the text non at the end of the label, but before. (see attached image). Would anyone know what could cause this problem, and if it is possible to print longer texts on Labels? Thank you Ondrej Mlecka Roma
