Issue with Bambu PLA Metal Copper Brown Metallic

I’m having issues getting the Bambu PLA Metal Copper Brown Metallic as It will not feed through the hot-end. The Bambu PLA Metal Iron Grey is fine. The Copper brown is much thinner than all my other filaments and it seems the extruder will not grip. It will purge if pushed through by hand. I’ve tried to use the AMS and manually but it still won’t work. I’ve also completed a Dynamic Flow to see if this helps too.
I’ve used my Bambu A1 quite a bit and believe the filament is too thin. Any support would be welcome.
