Rear brake disc on '14 FLHX

[Blade Guy]

Replaced rear disc about 2 weeks ago with an aftermarket "original part" disc. Noticed that the replacement had a button in it, the one I replaced was a one piece with no button. Have been noticing a noise from the rear of the bike. Turns out the ear of the caliper is rubbing the inside part of the button. Looking at all the aftermarket discs from the online parts houses they show the button. Going to dealer when they open and pick up (I hope) a disc that was original to this bike. Have any of you seen or had this issue? Thx.
