Expressions in Metrics in Grafana Alerting are being set as labels, which is disabling POSTING to Webhook URL

For some reason the expressions in the metric for my Grafana Alert are being set as labels ontop of the custom labels I already have, which is unabling me to make POSTS to a Webhook URL.

Is there a way to remove them? I tried everything and cant seem to get anywhere with this.

Thanks for the help.
