Player moving the Opposite Direction After Using Physics Constraint Actor

I used the Physics Constraint Actor as a method to “Grapple” the player to a certain place ([See Video][1])
in the video you can see that i print “W” and “S” to let the viewer know what the player is currently clicking.

but now I’m having a problem, after the player goes down from the grapple, I think (as I’m not sure if it really does) it retains the forward force implemented by the Physics Constraint Actor when it swing the player, whenever I press “W” to forward the player, it still goes backwards, only until a specific amount of time will i ever be able to regain control of my character.

this is just One of the Two Bugs I have encountered, the Second one is that whenever I grapple so fast, the character physics constraint just couldn’t keep up, sometimes it works, sometimes it wont…

Here are my Blueprints:
