Attaching cable to arrows

Ok two question here When using spawn actors I cannot use my own custom cable blueprint so i have to use the default cable actor. I do not know why that is the case.

So after spawning the cable into my game id like to keep it attached to the arrow as it flys. Currently it attach the arrow while equipping but once fires it doesn’t want to attach anymore so it just free floats there where the arrow stood. Keep in mind it is still the same arrow equip and fired. I do not understand why that is the case. I assume attach to actor just keeps it attach for as long as the actor exist.
