Bubble's Data API returning missing objects

Hi everyone! In my app, I have a User data type and an Answer data type. The Answer data type stores the value of the answer the user has provided to a question. The User data type has a field that stores multiple Answer objects.

The problem I am experiencing is that when I retrieve these answers using an endpoint in my node.js server, sometimes I am getting IDs of Answer objects that do not exist in the database. When I type those IDs in the database, nothing appears.

My question is how is it possible that I am receiving IDs from objects that do not exist? Is this a problem with Bubble’s Data API? Am I missing something?
