Trail Effect Not Straight?

Hey Boxers,
I wanted to set up some basic stuff for a new game I'm working on and noticed that the trail I added to my character is drifting to the right hand side?
Does anyone know what's causing this issue?

Here's a screenshot of the trail (not moving the character):


Thanks for reading,
Noah

 

My settings:
Start Width: 15
End Width: 5
Speed: 0 <-----This is why its tilting. Make it 0.
Length: 35
Wave Height: 0
Wave Length: 0

 

Ooh thank you
Had this problem with some of my apps, never thought it would be the speed!
