Still seeing some ALG-7 DNSSE

If I do:

cd /etc/named/working/main/
for i in *; do dig $i +dnssec | grep "A 13 2" | awk '{print $1}';done

I see a list of all the domains on the system, so that's good, everything has a ALG-13 signature.

If I do

for i in *; do dig $i +dnssec | grep "A 7 2" | awk '{print $1}';done

I see a list of a handful of domains that still have ALG-7 signatures. This is confirmed by a warning in dnsviz.

I don't see any differences in the configurations, and none of the main records on the registrar list ALG-7 anymore, only ALG-13.

All of the domains are setup with  dnssec-policy default.

Thera re still 007 keyholes on the system for ALL domains (unexpected), updated every hour  (expected).

This domain does not show any ALG-7 keys in dig:

# dig kreme.com +dnssec +short
65.121.55.45
A 13 2 3600 20210415161448 20210401155316 29597 kreme.com. Sea2LPlKGeH/aP1kwONwtuH0Jkp2TVHNb/v9PEOUiVQVzCwKMkg79+K9 bE8yhNQ2vLV4Fxvzk4jknP8Cbq98lQ==

Is there anything I need to do here or not? Will those alg-7 key files continue to hang around forever? Do I need to do something to get dnsviz and dig +dnssec to stop reporting the old keys or is that like propagation and it will sort itself out? I don't see a pattern in the domains that are still showing alg-7 but it is possible they had the DS/registrar info updated later than the other domains.
