Problème de trait sur Photoshop

[Catherine28909426awv5]

Bonjour je n'arrive plus à faire de simples traits, à la place ce sont de grosses flèches noires qui se forment... quelqu'un peut-il m'aider ?...

What are the Tool’s settings? 

[Catherine28909426awv5]

Same as yours I think

If I remove "end", It s better but I have rectangle, not a simple line, is there anything esle I could change ? nthank you for your help !

That’s the way the Line Tool works, but you can set the Weight to 0px or just use the Pen Tool.
