host_filters in INSTANCE FILTERS

Im syncing vcenter guests in to our Inventory, the problem is that im getting all guests from vcenter synced in to AWX, and i just want to have some specific guests.
I have tried to use host_filters in INSTANCE FILTERS but it didnt work, i got all vcenter guest. Syntax that i used: host_filters: {{ “part of hostname” in config.name }}

Were you ever able to figure this out?
