Error while trying to update deleted records

I am a developer and I have access to two accounts with sales hub professional subscription,
I came across a weird error,if we are trying to update a record(product or sale or customer) with Id which is already deleted in one hubspot account we are getting “Object_not_found” error response from v3 API and in another account for the same scenario instead of updation or error it is creating a new record.
I thought of configuration changes and compared both the accounts configs, But all are same.
Can someone help me with what may be the cause for this issue.
