Exactly, how do rangers favored enemy bonuses work in DDO?

The ranger gains a +2 bonus on Bluff, Listen, Sense Motive, Spot, and Survival checks when using these skills against creatures of this type. Likewise, he gets a +2 bonus on weapon damage rolls against such creatures.
At 5th level and every five levels thereafter (10th, 15th, and 20th level), the ranger may select an additional favored enemy from those given on the table. In addition, at each such interval, the bonus against any one favored enemy (including the one just selected, if so desired) increases by 2.
If the ranger chooses humanoids or outsiders as a favored enemy, he must also choose an associated subtype, as indicated on the table. If a specific creature falls into more than one category of favored enemy, the ranger’s bonuses do not stack; he simply uses whichever bonus is higher.
Now the in game DDO description doesn't say a thing, so I would hope/assume it works the same..
Yet that can be confusing. How I think it works in PnP: You gain +2 dmg/etc versus the first target your select at level1, at level5 you select a new target and gain +2 vs that type, but also the level1 version improves to +4. At 10 this increase again, given +6 to the first one, +4 to the second one and +2 to a new one.. Then at level15: +8 1st, +6 2nd, +4 3rd, +2 4th.

Does it work like this in DDO? I'd assume not since the order in which you selected them is not even listed in your character sheet. From what I can guess from my rolls, it seems the improved bonus stacks and applies equally to all favored enemies,, meaning +6 dmg to all 3 at level14.. And 15 we will have +8 to all 4, very powerful indeed. But I'm not sure on this.

The other thing is the skill bonuses - are they implemented/do they function correctly? I'd gather this could be tested for bluff easy enough, but the other would prove more difficult.
