Siser glitter adhesive residue?

[KYSIGN 233]

This is the first time I have used Siser Glitter HTV. I pressed at 320F for 15 seconds and peeled warm as per Sisers online instructions. It looks like some adhesive was left behind from the carrier. I have never had this problem from Siser easyweed. Any suggestions? Maybe I should peel cold or use less heat?

I always press for 4 seconds, peel the liner and pick away or lint roll any small particles of unwaned glitter then press 10-12 more seconds.
