Coinbase Prime seems to miss "CONVERSION" transactions

Hey,
I’m using Coinbase Prime API to get transactions using the “List Portfolio Transactions” endpoint
I did have a conversion transaction but it is not seen from that endpoint, however when calling the " List Activities" endpoint I can see that transactions’ activity and transaction ID

also, using the transaction ID I cannot get the data in “Get Transaction by Transaction ID” endpoint

Looking forward for your help.
