Can't copy across Custom Field and Label with wildcards

Hi there,

I can't seem to make this automation work. The label copies across as expected, but not the Custom Field - Priority.

Thanks for any help in advance. 

when an item is added to a checklist in a card in list "WORK IN PROGRESS" with the light yellow "{*}" label with custom field "Priority" set to "{*}", convert the item to a linked card in list "TASKS", set custom field "Priority" to "{wildcard2}", rename the card to "{cardname} | {triggercardname}", add the light yellow "{labelwildcard1}" label to the card, and add the purple "TASKS" label to the card
