Can’t play original MW on my PS4. Have the disc, just keep getting this message..

I have the original Modern Warfare disc and I’m trying to play it as I’m excited for the new one. Unfortunately when I put it in, it doesn’t work, just keep getting this , “add on..” message. Any help would be appreciated

those are the campaign multiplayer and spec ops packs cuz since activision decided to split them they are now called add ons but is not a problem let ur ps4 do its thing
