Plan: 2 to add, 0 to change, 0 to destroy.

Notice how there is only a single resource being shown as added but the plan shows 2. It is certainly possible that this issue is specific to our terraform state file. I am more than happy to provide both the statefile and the full config privately after redacting anything sensitive.

Expected Behavior

As there is only a single resource added both in code and in the plan output except for the end.

Actual Behavior

The number of resources added is magically 2 rather than 1.

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. terraform plan

Important Factoids

Nothing that I can think of. But I am willing to share the statefile and full config on something more secure that is not public. I have never seen this and I have been using terraform for a very long. This is
