Hello,
I've tried to solve my problem on my own but i failed. 2 of my vectors become transparent when i preview my project. How so? anyone has ever faced this issue and solved it? Thank you for taking Time to help me.

Before doing anything else, you need to check 3 things:
1 Colour transparency
2 Layer opacity
3 Layer blending mode
Refer to the manual [Help | Help...] if you don't know how to do these things.

Thank you very much for your fast answer. I can't believe it was so simple .i unclick colorize layer and it works. Thanks
