Space in value of CAA record

[ctapmex]

I have the following record for dns

:
  - ttl: 600
    type: CAA
    values:
      - flags: 0
        tag: issue
        value: letsencrypt.org; accounturi=https://acme-v02.api.letsencrypt.org/acme/acct/xxxxxxxx

There is a space in the value before 'accounturi'.
The dns record is added to server without errors. But when synchronizing dns and local storage, an error appears:
