That must have triggered an update from GoDaddy. If you have DNSSEC enabled (and plan to continue paying for GoDaddy Premium, which is required for DNSSEC signing) you might as well re-publish the DS record. This is normally automatic if you enable DNSSEC on a GoDaddy hosted DNS zone. If it isn't automatically added in a day or so, you should disable, then re-enable DNSSEC to get a published DS record for your DNSKEY KSK (flags=257).
Or you could add them yourself right now:

but this might mess up the automatic updates.
