I go to the Donation Corner and it says 11 items are up, but I only see 4. I reloaded and now it says 8 items are up, but only shows 2. Now it says 7 items are up, and shows nothing. Is it something on my end or is it glitching out?

Neither. Since they changed the DC it's not showing all/the same items for each user (I think it goes by alphabeth). You may see none, even though it says there are x items in there. You need to keep refreshing, until you see anything at all or to cycle through all the items. Meanwhile other users may have been lucky and seen/taken stuff. I myself find it pretty annoying at times. Esp. the uneven number of the filled page and also miss seeing the donators.
