Signature Variable Attributes broken v3.0

Zammad V3.0

When including a URL that is generated within the signature of each ticket, the generated URL is broken and not being translated with the correct values.

[#{config.http_type}://#{config.fqdn}/#ticket/zoom/#{ticket.id}]

Becomes:
......#x_%7Bconfig.http_type%7D://#%7Bconfig.fqd

The text printed in the email is however correct.

Sorry, I tested this and can’t confirm that.
Please provide the needed information to (maybe) help you.
