Cable component becomes straight when character is in motion (5.3)

I have just updated my project from 5.1 to 5.3. Everything works fine, but I noticed that the cable component in my character blueprint doesn’t respond to any physics and snaps to being completely straight, essentially forming a tube from start to end points, whenever my character is in motion. When there is no motion, the cable responds to gravity and forms an arch. This only happened after I updated the project. Any ideas?
