Spell Cast rolls damage twice

Hi,  Im new to this, maybe this is noob question but there i go: Im using D&D 5e (Comunity Contributed) Character Sheet, in my party there is a Level 4 Wizard, when i cast Firebolt or similar 1 damage dice spell, it rolls twice as much dice... why? how can i stop that? Thank you very much in advance!

Ah! Sorry, and i must say i turned off for all rolls the Auto-Advantage (that makes no difference for damage) so that should not affect this. (Sorry for my english)  Thanks again in advance.

When i look at the details for at the DMG result it gives me something like this: I don´t need (or understand) any of those modifiers for a Cantrip that only does 1d8 dmg... Maybe that is the error?

The dice roller does not know if you will crit in advance. It must roll all dice that might  be needed. Roll templates are capable of hiding the dice that were not needed, but they are still rolled. 3D dice do not have this capability. They are just a physics engine. They will always show all the dice rolled, regardless of if they were needed. As for the number of modifiers on your roll template, that's likely due to how the sheet is set up. I would not recommend the community sheet. It is very out of date and has limited interaction with the compendium.

Oh! Thank you very much! that helped a lot to understand what was happening. I should test some other sheets before enter all the data, i guess. Thanks again.
