What caused a given Contact ID to map to another one. On pasting some IDs into the Portal URL for a contact it opens the contact but the URL changes to a new one with a different ID.
If I call the HubSpot API with that same ID it also returns the data but the record ID is mapped to a different ID as the Portal URL does.
The problem I am having is that I have data that was synced with Fivetran into a database and I rely on that to read as a source to make updates to HubSpot via file imports into the HubSpot portal, but the IDs that have this problem are rejected on the import as not being a valid record ID.
To find work arounds for this I am trying to understand how this happens in the first place
