Lol, everything shows up. It might not even be a community thing, my profile shows I have 5 posts but if I go to the posts section of the profile nothing shows up.
i think the servers are a bit wonky at this time due to the influx of new users. there will probably be stability issues for a few weeks until things normalize. you can try clearing your cache? that might help.
Seconding this, some updates and changes seem a bit slow to follow through even when they're confirmed to have saved. OP I wouldn't worry yet, hopefully things will sort themselves out given some time.
