pfSense 2.5 acme .0.6.9_3 new txt record purge fails for DNS-Azure

[bottkars]

Hi all,
i recently upgraded to pfSense 2.5.0 and use acme 0.6.9_3
I use DNS-Azure as Method.
Re-generating Certs works firn, however i face an issue with Creating New Cert Requests.
When adding a new Domain, the _txt record getś created and validated successfully, however, upon purging the Text Record the request times out.
What concerns me is that the purge talks to Cloudflare DNS .....
