I see you just copied them off of MCI(MCI is the only website to use names like "Strength Splash (6:00)" instead of "Splash Potion of Strength (6:00)" so that the names fit on one line on the ID Page. Well it and anything that just copies from it).
Would be simpler just to put a link to MCI if your just going to copy/paste from it (So that the information is always up to date. The ID's were updated on MCI on 19th and it took almost a week for you to post here).
The list was copied off Minecraft Info at the end of 2011. Invisibility potions weren't around then. Forum posts are generally never updated after a person copies the information off of a website. Your better to look for the ID's from a website which updates its ID Lists (One which doesn't copy and paste but which gets the information its self).
