Just looking at the first plot we see that the distance (along a pependicular ie closet approach) between 1624 LOP and 1624 DR is not equal to the to the distance of the advanced LOP and the second DR. IE it is not properly andvance.
The easy way to advance an LOP is as checked above.
Your problem is compounded by the use of AP in the plotting. Avoid in the advanced LOP. Or if you do want to start from the AP for first LOP then add to the intercept azimuth vector the vector between DR1 and DR2 in plotting perpendicular LOP.
