[Koha] Mini Material Type Icon

[Caitlin Kleinpaste]

Does anyone know how to change the mini material type icon?  I'm using
3.20.03.000.

When we imported, it seemed to randomly decide that some items are books
and others are not, regardless of what they actually are.  It's confusing
to the patrons when a DVD is listed as "DVD" in location and "Book" in
material type.

I've looked through the marc records and done lots of googling but I can't
seem to figure out what codes for this.
