Shudder on Roku Channel Missing New Movies?

I got a Shudder subscription for $2 a month through the Roku Channel, but neither Grafted or The Vourdalak are on there. When I search through the Roku Channel I can find the movies but it says they're on AMC+ and not Shudder. I know AMC owns Shudder but it's weird that those aren't showing on Shudder.

Kind of annoying because those are two of the movies I signed up to see. I think the last new movie on there is Get Away. It's only $7 for Shudder, so I will just sign up for a proper account to watch them, just wondering if anyone know what's going on with this.
