Bug with i18nOutput & aria-label

I have the following span: < span  class= "popover"  aria-label= "Damage Value"  data-i18n-aria-label= "damage_value-u"  data-i18n= "dv-u" >DV</ span > While following the instructions here , the output didn't seem to include the damage_value-u key, so that the label now shows up as: aria-label= "[damage_value-u]" Am I doing something wrong, or is this a bug with the function?

If it's just a couple of aria-labeli i18n that's missing, you can just manually add them to the json. But wouldn't be surprised of Roll20 didn't detect "data-i18n-aria-label" as a thing. I only found two used of them from prior sheets.

Yeah, I've already patched it manually, but wanted to see if I was making a mistake or if this was a genuine bug.
