Affected Resource(s)

Please list the resources as a list, for example:

• ns1_record

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

Debug Output

      ~ regions {
          ~ meta = {
              ~ "georegion" = "EUROPE" -> "US-CENTRAL,US-WEST,US-EAST"
            }
          ~ name = "EU" -> "NA"
        }
      ~ regions {
          ~ meta = {
              ~ "country" = "RU" -> "CA,MX,US"
            }
          ~ name = "EU-RU" -> "NA-US-CA-MX"
        }
      ~ regions {
          ~ meta = {
              ~ "georegion" = "US-CENTRAL,US-WEST,US-EAST" -> "EUROPE"
            }
          ~ name = "NA" -> "EU"
        }
      ~ regions {
          ~ meta = {
              ~ "country" = "CA,MX,US" -> "RU"
            }
          ~ name = "NA-US-CA-MX" -> "EU-RU"
        }
      ~ regions {
          ~ meta = {
              + "georegion" = "SOUTH-AMERICA"
            }
          ~ name = "REST" -> "SA"
        }
      ~ regions {
          ~ meta = {
              ~ "georegion" = "SOUTH-AMERICA" -> null
            }
          ~ name = "SA" -> "REST"
        }

Expected Behavior

Without any change in the config, there shouldn't be any delta shown in the plan.

Actual Behavior

On every single plan, the order of the regions changes and hence forces us to do an apply. However, after this apply, we still see the same diff.

Steps to Reproduce

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

1. terraform apply
