BTT Smart Sensor Pauses after Prime Blob, Doesn't detect during print.

I installed a BTT smart filament sensor V1 (SFS) and when I start a print during the prime blob it goes from "active" to "empty" in mainsail and pauses the print immediately.

Then to be sure, I snipped the filament before it went in and it didn't detect the runout.

I put the macro in the user overides config but I might have missed something somewhere. Appreciate any help. Config included.
