Is Adobe Stock not for prime time?

We've been testing the stock library service from Adobe for a while and just downloaded a batch of 7 clips for a project. There are a few features missing from this library service that I won't go into here (e.g., no batch purchasing option), however the key issue that is making us think maybe this isn't a serious offering from Adobe is the following: every invoice (again, no batch processing, so we have 7 invoices to process) contains a 'product id on the line item.' Presumably, this would be the clip id from the library...however, while trying to manually link each invoice to the actual clip it references, we noticed that every invoice has the same product id...and that id is for a clip that we did not purchase. So, effectively, we have 7 invoices for the same clip that we never downloaded and licensed. Anyone else have this issue?
