Smart Dimension Problem

Hello I am Tej Pratap.

Suddenly today my smart dimension tool is not working properly.

I am able to give dimension one time only after that it won't allow me to select another line or circle etc.

A smart dimension icon is coming next to my cursor.I am stucked at this.

This is very frustrating . Angle between two lines is also not being changed.

Without this i am unable to do anything.Please help

For your info i am running SW 2016 SP1.0

This pic displays what cursor looks like-(This pic is after giving dimension to the line. but dimension is not appearing there.
