I have same issue with Unreal 5.4

I found dumb temporary solution for this to trigger construct script. tick “Input Spline Points to Construction Script” in Spline Details.

But you need to untick and tick again every changes on your spline point

You can also move it to the point to where you want the spline to end, and let go. Then move it again, and undo (Ctrl Z) and it will update. Slightly faster than clicking boxes, if you prefer.

The issue has been discussed here, see my post for the issue ticket which you can upvote to prioritize it: Editing a Spline as part of a Blueprint Construction Script .. (UE5.4) - #6 by Sly.Sk

You can upvote the reported issue here: Unreal Engine Issues and Bug Tracker (UE-212309)
Hope this will be solved in a fix update because it can break a lot of projects with construction scrips.
