Joomla 4 icon issue

I am trying to use Phoca PDF
I am able to use it with the default Cassiopeia template here:
mcyc.your-portland.com/index.php?option=...icle&id=4&Itemid=184
But not with my CK template here:
mcyc.your-portland.com/index.php?option=...&catid=31&Itemid=200

HI
I have no idea how works Phoca PDF. You shall ask them about the possible cause of the problem so that I can investigate into Template Creator CK
I think that this can be related to the overrides, but without technical informations I don't know where to check that
