Reference problem

Hello;

I'm new to draftsight and I have a small problem

I'm trying to draw a line with a reference point. When I point to the desired point in ref I have a small blue cross that appears. I indicate the direction I want and I type in my value. However, when I do like this, the line is still drawn on the ref point and not at the desired distance. 

I looked in the parameters of Esnap but I have no idea what causes this 

Ps: Draftsight v.2018

Thanks in advance!
