There are some possibilities that come to mind:

1. The draw function may never be called, try adding a print before drawing each enemy to see where or if at all it is trying to draw it
2. You might be drawing something after the enemies through which you do not see the enemy
3. You're using love.graphics.translate and are actually drawing offscreen without realizing it
4. You never add any enemies to the table
5. You might be calling love.graphics.clear at a wrong time

Setting color to full white before drawing an image with default color mode means drawing the image using full colors of the image, i.e. drawing as is.

Code:

if gamestate == "lvl 3"  then -- If my game is in the 3rd level.
        enemycreate(128,32,"right")
   enemycreate(256,32,"left")
   end

Code:

function addline(text)
    LineNumber = LineNumber + 1
    Lines = Lines .. '\n' .. text
end

• Replace Lines = '' by Lines = {}
• Change addline to
  

  Code:

  function addline(text)
    if #Lines > 100 then -- something like that
        table.remove(Lines, 1)
    else
        LineNumber = LineNumber + 1
    end
    Lines[#Lines+1] = text
end

• Change the drawing code to: (you might want to experiment with that)
  

  Code:

  for i, line in ipairs(Lines) do
    love.graphics.print(line, 0, 780 + (i - LineNumber) * 14)
end
