How do you select dimension end points in SW 2024

We have recently "upgraded" to SW 2024 SP3. several people have noticed that they cannot select dimension end points anymore. the attached picture is an example. the dimension end point is located a distance from the center mark. the user would like to have the end point located closer to the center mark. previously you could selected the blue square "dot" circled in red and place it where you would like. now you can't seem to select that point.
