Cannot edit core abilities D&D 5e Character Sheet

I am unable to edit any of the core abilities on the sheet (STR, DEX, etc), only their modifiers. I don't know how to fix this. Thanks in advance.

Can you post a screen shot to verify which D&D 5e sheet you mean?

Here you go.

Yeah, that's the D&D 5th Edition by Roll20 Sheet. But I have no idea how one could click on and change the modifiers (the 0s) and not the scores (the 10s). They are not even selectable fields. Are you running any injected scripts or extensions that change the behavior or Roll20? You could try editing the sheet values while it is not popped out into its own window, but I don't think that's what's going on here.

I checked the wiki page to learn how to use it, and it said I was able to directly input the values into the fields. Also, I thought the bottom (10's) were the modifiers? That's how I've done it anyway. As far as I'm aware, I'm not using anything that might change Roll20. Is it that I have the sheet backwards, with the modifiers being what I'm unable to select?

I've figured it out. Thank you!

the single-digit thing is the "modifers", and the number that is "10" by deafult is the full "attribute score". Seems you're just confused in which was which. When you update the attribute score, and then select something else, the modifier will update.
