You paid for 12GB but the GPU lottery decided you're getting a mystery number instead. Could be 12008MB, could be anything really. The question mark is doing some heavy lifting here, like it's actively uncertain about its own existence. Your AMD Radeon is out here playing roulette with VRAM detection, and Windows is just shrugging like "yeah idk man, somewhere around 12 gigs probably?" Nothing says "enterprise-grade hardware detection" quite like slapping a question mark on the number. At least it's honest about not knowing. Better than confidently reporting the wrong amount, I guess.
