Ok. I didn’t thought about that. I tried to create the scenario in another project but I’m getting the same results. And I did the same thing in a previous build that I have (4.8.3). In that case it works perfectly. I saw in another thread that there was some changes/fixes in the spline component. I don’t know if is that the case. These are my files. Let me know if you need something else. Thanks anyway.
