[13th Age Official] Basic Attack buttons on sheet are not working, right?

Hello guys, been using the 13th Age Official character sheets, and I noticed that every time I click on the ranged or melee attack buttons, die get rolled, but the result displayed on the basic attack card is always 0 for both attack and damage. Why is this happening?

You have to fill in a melee weapon and select it. For example, Longsword 0 d8

There are weapons registered and selected, the power card displays the weapons but they still come out as 0 and 0 when the card is clicked. If I hover over the 0's, there's the roll formula, it isn't being displayed on the boxed tho. It seems I have to place a 1 Value on the 0, however that also raises my attack and damage. EDIT: I copied my player's sheets and it works now, also when I make a new sheet, I don't know what happened, but thanks :D
