Email command Not Updating

Email command Not Updating

I am attempting to configure Email Commands before going live, I have two custom fields, one called Tracking and one for Return Tracking for tracking#s of replacement equipment to be RMA'd. The subject command is set to @SDP@, I opened a test ticket and replied to an email to my test requester with the fields to be auto updated in the ticket from the email.

@@Tracking=1111@@
@@Return Tracking=1234@@

After sending the reply, the ticket did not update those fields. I am sure I am doing something wrong
