I have a rough alignment in a river with two additional alignments on either side that represent the toe of slope. I created a template that essentially represents a river bottom with 2:1 slopes on either side. Whenever I try to add a point control that locks the toe of slope in my template to the toe of slope alignment, I get the behavior seen in the image. It appears that my point control extends to a farther portion of my alignment rather than the closer portion. In my template I have tried setting a horizontal max and that still does not work. I found a similar question asked in 2017 located here: Point control by horizontal alingnment in Road Designer - OpenRoads | OpenSite Forum - OpenRoads | OpenSite - Bentley Communities and was curious if this is still an issue 6 years later or if there is a way to fix this. I would like to avoid splitting up my alignments because this is a very long and winding river, and I would end up with about 10 alignments or so.
Are you able to share the file/data? I see you have clearly delineated edges for the stream bottom, why not profile them and create a terrain incorporating surface templates? You could run the stream banks as linear templates on the edge. If you can share the file, I can try to work something up.

We may still have some issue so best is to provide file through a Service Request.
A quick test worked well from my side:
Have you tried Target Aliasing? Here's a short video to explain how that may work for this situation. https://www.youtube.com/watch?v=kfhLA4DUqrQ

We've encountered this problem for years. The best way we have found to overcome this flaw is to model form the outside in instead of from the centerline out. Determine/estimate the maximum offset to each side and add a null point in your template to each side that is 30 beyond the maximum estimated offset. Point control the null points with the same constraints applied to the point controls that are failing in some locations, but make certain to leave the null point +30 beyond the maximum offset.
as an example: NULL_RT has horizontal constraint of 130 from the CL and a slope constraint of -2.00% from the CL
Change the parent of RT_Point (the one that isn't working as desired) to be constrained to NULL_RT. The constraints on RT_Point will be Slope=-2.00% from NULL_RT and Horiz=-10.00 from NULL_RT
By changing the horizontal constraint of RT_Point to NULL_RT the seek direction looks 'backwards' toward the centerline, so the point controls usually solve as expected, but you never really know. Software is like a box of chocolates.
