Hmm. Not sure why you are getting the blank line. Can you see what command is being sent when you click the battleaxe name in chat? (Click the name, then hit the up arrow in chat to see the last command run). As for the extra d10, that is because a battleaxe is versatile (1d8 when wielded in one hand, 1d10 when wielded with two hands). The d10 is there so that you do not have to account for that when attacking, simply use the die roll that you need at the time. However, I would recommend adding the Strength Modifier to the d10 roll so that the total damage is calculated for you.
