DRAFSIGHT PB display of all traits

Hello 
I have a problem on a Draftsight plan. As soon as I open this plane, I can only see a few lines on my plan, I can select them, move them, but I can't see them. 

What can I do? 

I factory reset  and even uninstalled and re-installed it, but nothing changes. 

 

A colleague opened it on AutoCAD and it works very well so I don't understand anything anymore

I made the plan on Draftsight

Thank you for your help.
