Slack notification adds {pulse.XXXX} before every auto populated field

When setting up a Slack notification automation in a specific board, I am using the auto poupulated frields from board items but its adding “pulse.________” to my item and messes up the automation. Anyone know how to resolve this? When the notification pops up in Slack, it doesnt populate the board item.
