I think the issue is that every addon has it's own functions and sometimes the library calls a function from on addon's file, and sometimes from an another addons file, which could create mismatch numbers even in global variables. If every addon updates to a version which won't let the lib load twice or load an older versions the issue will be gone.

You can eliminate the problem by putting this hack into the Lib_ToggleDropDownMenu funcitons, however you gonna need to put this into every addon's function:

for i = listFrame.numButtons + 1, 1000 do
    local button = _G["Lib_DropDownList"..level.."Button"..i]
    if button then
        button:Hide()
    else
        break
    end
end

Also this only deals with the visible issues the global mismatch between addons still gonna reamain. The total solution is that the versioning system which will only allow one instance of the lib and it's functions.
