dnsimple_domain_delegation resource: Error: Provider produced inconsistent result after apply

[robacarp]

I'm migrating our DNS records over to Route53 so we can better use Alias records. In attempting to update the dnsimple_domain_delegation resource for our primary domain, it produced this error (and didn't make any changes):

│ When applying changes to dnsimple_domain_delegation.primary_domain, provider "provider[\"registry.terraform.io/dnsimple/dnsimple\"]" produced an unexpected new value: .name_servers: planned set element
│ cty.StringVal("ns-1432.awsdns-51.org") does not correlate with any element in actual.
│ 
│ This is a bug in the provider, which should be reported in the provider's own issue tracker.
