Ue4 4.27.2) PhysicalConstraintComponents are spawned on wrong position




Constraints keep spawning at the world’s origin.
so I manually set the position with Blueprint


however, the component spawned at the origin of its relative location now.
(I checked that the two relative positions are not the same)
(I also made the same thing with Cpp, I put the same logic in the constructor and overriden Begin play function, Despite, the tries, It doesn’t work)
so, I googled around but there was no good solution for it.
Please help me resolve the problem if anyone knows how to deal with it.

thank you for reading my trouble.
