Questions regarding relative waypoint

I have a moveJ to a fixed position PT1. Then I set a relative waypoint to the next position PT2.
In the setting for the relative waypoint, it has “from point” and “to point”.
When I set the “from point” to be exact PT1, then I moved the robot and set the “to point” be PT2.
When I run the program, I see the robot skip PT2. Why? How to fix it?

Do you have large blend radius values on these points? The blends may be overlapping causing a skipped waypoint. Check your log screen for messages about overlapping blends.

Also, if you have a blend in point 1, the robot will not stop moving. It will move close to point 1 within the blend radius, and then continue moving to point 2. If you want to make sure the robot stops at point 1, make sure there is no blend radius on it.
