I'm seeing some strange values for movement ranges on my units in a tactical battle. The situation is thus:

My soverign has Tireless March active, and is mounted on a horse. She has two movement. shouldn't she have 5 moves in tactical combat? Default 2, +2 for the horse, and +1 for tireless march ?

A random dude, on foot,  with a warhammer in the same army army (not a champion) has the Charge Trait. On the first turn of battle he gets 8 movement (!) and each turn afterwards, he has 3 movement. Again this is not as expected. I'm not entirely sure how tireless march is supposed to work, but the values i'd expect would be 5 movement on the first turn (+3 from charge trait) and 2 movement any other turn.

Or if he's supposed to get a buff from TM, then 6 and 3.

\from whence comes this 8 movement ?
