Eldrich Cannon On Character Sheet

I don't know if anyone else has this issue, but for my artificer character with the eldritch cannon ability, it says the three options of flamethrower, force, and protector are available, but only the flamethrower shows up as an actual attack/ability. Also, when going to the details of the flamethrower or force cannon, it says the attack roll is 2d8 +3, but it doesn't say to add the INT modifier, which it does for the protector cannon, but that one doesn't show the +3. Are these bugs? It would be great to have the force cannon also show up as an option, as the flamethrower does. Not sure, as I'm not very experienced with D&D Beyond, but thanks in advance!

This is a current system limitation. Adding an attack roll automatically adds the modifier to the damage, which is why those attacks are hidden by default. If you do customize them to Display As Attack, I’d recommend also adding a negative damage bonus (in your case: -3) to cancel out your INT.

This is the kind of thing where it'd be great if there were some kind of note or documentation about this in the character builder or on the sheet. I understand the need for it to work the way it does, but I think the vast majority of people are not going to figure that out on their own.
