The character sheet tends not to update when things are converted, Maehlin’s Hubris gloves are an example of this. As long as your character doesn’t move faster when you have haste, it’s probably working properly.
But if you think something’s bugged, the devs prefer you to report it using the in-game bug report tool.
The attack speed penalty is also applying twice for some reason. Once when you put the point in and again when you equip a a shield with a 2hander. That seems like a pretty bad bug.
