I have create a custom variable called Env with key and pair for example
Prod : wd_env_physical =“prod” Then in the markdown, when I use it like ### ${Env} metrics by Data Center. It shows the value(wd_env_physical =“prod”) not the key “Prod”. Anyone can help will be very appreciated.

Are you trying to use the variable in the Panel Title or some place else (maybe share a screenshot for more clarity)?
Thanks
