I made screenshot from “Admin menu access” add-on opened for ‘Administrator’ role at User Role Editor:
But menu should be available in order to see it at “Admin menu” window.
I suppose that you may lost shown TablePress capabilities somehow. Check if they included to your ‘Administrator’ role. If not, try to reactivate TablePress plugin. In case it will not recreate its capabilities during activation, try to add them to ‘Administrator’ role manually.
