Multi-overlaps in trigger with spline movement

I have the ladder in level, when player press E he can climb up to the ladder by spline movement (timeline → get spline location at time → set player location). But this ladder have trigger box, when player begin overlap - play sound. But this trigger overlaps many, many times. I think its becouse “set actor location” works like a teleport and trigger update on this teleports. How to make “set actor location” without updating triggers, becouse player already IN trigger.
