What is your strength modifier? If you don't have anything else that is sent as part of this roll, I'd look for attribute values that are corrupted.
Strength modifier is +5, and I have no idea how to look for corrupted attribute values. I've made new sheets and it still works, but my players can still use their attacks fine.
I found out what was going on. It was in the damage modifier I had active from the sheets Rage damage. In the damage type, I had put [[Weapon]] as my sort of just saying "Whatever damage type the weapon is". Got rid of the brackets, all good now. Forgot brackets have actual coding implications. This is what it looked like, I deleted the [[ ]].
