Hero Equip Gear Bonuses?

So, the inventory shows bonuses when looking at gear that does not show up in the Hero Equip screen. For example, the Epic Soldier Boots from the inventory have a listed bonus of +3% Infantry Attack. But, none of these show when equipping gear, and the stats do not reflect these bonuses.

So, what's up with this nonsense? Are there bonuses on more than two or three items, are these other ones placeholders, is the coding not complete, what's going on with this stuff? Would really be nice, since the inane changes to the Epic Boss could really use these bonuses to help folks along, since we all already know that, despite damage output not changing much on the user's end, the HP is almost certainly going to increase again.

I have units with false bonuses too.

Equipment that have actual bonuses apply whether or not they are equipped.
