Issue is there is no catalog sku reflect in ticket

-so what i made is when ever a ticket raise to IT > it set Type to IT > Other (worked)
and added a new field as service catalog:

-issue is whenever you choose in catalog it reflect in service catalog (it doesnt work at all_ )
Works is if it was mouse > catalog will be mouse
laptop > will be in catalog laptop
but still it dosent reflect in “serice catalog” filed ? why and how to solve it.
