        }
        (5 unchanged blocks hidden)
    }

Actual Behavior
terraform plan output show all tags on root_block_device as new changes every time I run terraform plan even if these tags were already added to root_block_device by the first plan/apply.

Expected Behavior
If a tag was already applied to root_block_device terraform should not show this tag as new add tag on plan output for each plan.

Steps to Reproduce

  1. terraform plan; terraform apply : The root_block_device volume will be created correctly with all tags in tfe file.
  2. terraform plan again. terraform plan output show all tags on root_block_device as new changes with + sign
