Yellow Constraint Line Not Visible in PhAT

Hey Guys! I’m using PhAT and following along with the video tutorial on YouTube. But, as the video shows a yellow constraint line as a guideline. I’m not able to see that.

Can anybody tell me why?

Thanks.

In case someone wonders why, they added colored constraint lines for each axis(red, blue, green). There is no more yellow line as is shown in the tutorial video’s.
