In Pega Smart Dispute do we get transaction details from VISA automatically ?Or in Pega we need to map?

We are using Pega Smart dispute for issuers,and its built on Constellation,now we have a transaction tab where certian fields are empty so does VISA sends these value or is it from pega end that we need to map?(Fields like Merchant/Payee name,Authorization amount etc are blank,how to get these values of the missing fields populated?)

In the UX Tab i checked this is its configuration so how can i check the mappings?as its added in Tab layout of full case view:
