Hi. I believe you’re referring to transactions that were made on the Epic Games Store, which is separate from the UE Marketplace. I suspect that you’re looking at your Library under Unreal Engine, which will show your Vault of UE products acquired from Marketplace. The two products you mention won’t show up there.
Instead, transactions from the Epic Games Store will show up on your left nav bar as (a separate) Library in the launcher under Epic Games. I hope this helps.
