This is because we are using the v-bind directive without arguments in a few places, binding an entire API response object to a given element on the page. This was convenient in the beginning because we weren't always 100% sure what properties from the object we might need as we were adjusting the initial designs, etc. But I can see how it could be confusing or problematic.

In cases where we still need to pass down a large number of properties to a child component but don't want *everything* from a given object to show up, we should probably create a new computed property in the parent that returns an object containing only the properties we need.
