How to create a simple BP for an enemy to slow his movement speed down when he is going over a box collision which should trigger this ?

Hmm there is something wierd when they transition from one trap to the next one just in in between those 2 traps in a row. It seems when i have 2 traps after another in sequence when they walk over the first trap and when they step to the next one they are still awso with 1 foot on the first one so for a split second they get another -100 to movement speed when walking over those. here is how it looks like

So this isn’t the best approch to make this to work then the movement speed need to stay constant all the time even if i put 3 or more rows of those after another it will look very wierd… Is just some wierd split second animation that they get even slower and then back to -100 one movement speed debuf instead of 2. Maybe i should decrease the collision box area and that may be working for the smaller guys if some bigger ones comes with feet as big as the trap they may step and trigger 3x -100 movment speed if they have 1 foot on lets say 2 traps and the next is on the third … hmm
