I am pulling in a couple custom properties into our Slack alert but trying to update with a new custom property of address and not pulling through in the alert. As you can see the other custom properties are pulling through just fine. I also added the address to our email alert and that is coming through just fine. Here is the slack alert and the code used for it. Any help would be appreciated.

payload={"text":"${N=SwisEntity;M=Caption} is DOWN", "attachments":[{"text":"Alert: ${N=Alerting;M=AlertName}. Click <${N=Alerting;M=AlertDetailsUrl}|here> for alert info. \n Please acknowledge <${N=Alerting;M=AcknowledgeUrl}|here>. \n CID: ${N=SwisEntity;M=CustomProperties.CID} \n Address: ${N=SwisEntity;M=CustomProperties.Address} \n ${N=SwisEntity;M=CustomProperties.CarrierContact} ", "title": "${N=SwisEntity;M=Caption} is DOWN. ","title_link": "${N=SwisEntity;M=DetailsUrl}","color":"#FEE529" }]}
