There's definitely a line there, no doubt about that.... but since it's a dollar tree, it makes me think evap. Only because they're really not that sensitive and don't normally show a line that early. Try and get a picture of the next one while it's wet, and if it shows a line, try another brand to back it up. Good luck!
