Copied cert to Webmin and Usermin is not detected in 'Manage SSL Certificate'

Hello, I like to get me cert files auto-copied to Postfix, Dovecot, Webmin and Usermin after a Let's encrypt renewal.

First, I created a self-signed cert for my Root domain and pressed all 'Copy to *' buttons under Server Configuration->Manage SSL Certficate->Current Certificate. The status showed 'This SSL certificate is already being used by : Dovecot, Postfix'. The copy to Webmin and Usermin did not get detected.

Then in created a Let's encrypt request. The log showed: [...] Copying certificate and key to /etc/usermin .. .. done Configuring Usermin to use them .. .. done [...]

I assume that the copy to Usermin got detected, but was not displayed in the status of 'Current certificate' tab. The certs to Webmin were NOT copied. If I return to the 'Current certifcate' tab, status shows: 'This SSL certificate is already being used by : Usermin, Dovecot, Postfix'.

Hope for a fix soon. Meanwhile I setup Let's encrypt renewal additionally in the Webmin configuration. Instead of detecting or saving copy operations, wouldn't it be appropriate to have own copy options in the Let's encrypt tab?
