Sorry to hear this Leo… if this behaviour doesn’t seem expected please reach out to our support team as our technical specialists will be able to investigate 
Regarding automations/integrations on template boards, all automations that are turned on will duplicate over to the templated board. In regard to custom recipes using apps and integrations at this time these are NOT supported in the board duplication/templating process. These recipes will not duplicate over. (ie: Gmail / Outlook/ Slack/ Apps). I apologise for the setback here
Please cast your vote on the existing feature request to put greater emphasis on this need and get this on our developers radar!
