Hi Marcin,
I think there is a small bug with itemize and columns: in another thread (with
Subject « vertical alignment problem in column items» ) Dalyoung reported also
an issue, which is related to what you have observed.
Please see my message in a reply to Dalyoung's message, where I reported some
testings but I am not sure when this bug appeared (in mkii, the behaviour is
essentially correct).
Best regards: OK
