Good day

I need advice please. I have converted a Koha installation from 2 to Koha 3.

Now there is a "syncronization" problem between the items table and the marc record in bibioitems.

To make a long story short, the itemtype appears in the marc record, but not in the items table.

Is there a procedure how to syncronize those 2 "fields"?

Thanks for any advice!
