I get the spec just fine.

With

 if db.stats then

Your Update function is:

local function Update(self, t)
                if playerRole == nil then
                    Text:SetText(hexa.."No Stats"..hexb)
                else
                    if playerRole == playerRole.Tank then 
                        UpdateTank(self)
                    elseif playerRole == playerRole.Healer then
                        UpdateCaster(self)
                    elseif playerRole == playerRole.Damager then
                        UpdateDamager(self)
                    end
                end
            end

playerRole appeares to be a table so it can't be both not nil and == a sub-key of itself

if playerRole == playerRole.Tank then

is essentially

if theTable == theTable.Tank then

You need to re evaluate

local playerRole = LibClassicSpecs.Role

and maybe add an other variable to hold the actual characters role name string.
