Ulduar no longer has 10 and 25 modes, that was changed Patch 7.3.5.
If you are entering the raid on your own it just has Normal mode, which scales up to 30 players.
The achievements for this raid also got merged down so it only has one setting instead of being split between 10 and 25.
Ulduars loot also got changed so both 10 and 25 items will drop in there now too.
Wowhead put together a fantastic guide for this during the launch of Patch 7.3.5, you can find that here:

PS: If that's happening in other raids, try changing the settings while inside.
