• In your snippet the staff name is "perc", in your dump is "perc." but, even after changing it, I found no difference in the result.
• Using your dump routine I get:
  
  Code: [Select · Download]

  { 
     ["Name"] = perc.,
     ["Group"] = Standard,
  } 

{
  ["Group"] = { ["Text"] = Standard, },
  ["LabelAbbr"] = "abbr",
  ["Label"] = { ["Text"] = label, },
  ["Name"] = { ["Text"] = perc, },
}

local Name = Item.Opts.Name.Text or Item.Opts.Name
local PercStaffNumber = string.match(Name, PercStaffName.."(%d+)")

print(dump(Item.Opts))

function dump(o)
   if type(o) == 'table' then
      local s = '{ '
      for k,v in pairs(o) do
         if type(k) ~= 'number' then k = '"'..k..'"' end
         s = s .. '['..k..'] = ' .. dump(v) .. ','
      end
      return s .. '} '
   else
      return tostring(o)
   end
end
