Draftsight Snap Perpendicular with "3 Points"

Hello

 

On Draftsight, I regularly encounter an issue with the perpendicular Snap.

 

The perpendicular symbol is followed by 3 dots and when I click on this hook, the line is absolutely not perpendicular, nor even attached to the hook line.

I have attached two screenshots

 

Have you ever encountered this problem?

 

Thank you for your help =)
