Glad that I was able to be of assistance.
The logic still feels wrong. Separating creation and visibility of objects is a good start.
Don't see the reason why

if not currency[counter].tooltipinfo then
                    currency[counter].tooltipinfo = link:match("|Hcurrency:(%d+)|")
                else
                    currency[counter].tooltipinfo = link:match("|Hcurrency:(%d+)|")
                end

can't be simplified into

if not currency[counter].tooltipinfo then
    currency[counter].tooltipinfo = link:match("|Hcurrency:(%d+)|")
end

I think

elseif not isWatched then

can be changed into

else

.
