Multiple undeletable TXT _acme-challenge records

Hi. domain has a shared Cloudflare Universal SSL certificate on the edge certificate that is Pending Validation and is not being renewed.
As a trial, I tried to manually issue a Let’s Encrypt SSL certificate, but the following error occurred and I could not create it.

No TXT record found at

So I checked the _acme-challenge TXT records with the command below and found a lot of _acme-challenge records.

dig -t TXT

This is a record that does not exist on the DNS page.
I tried to delete the TXT _acme-challenge record using the steps below, but I am unable to do so.

  1. Disable Universal SSL
  2. Delete via API

what should i do?
