transform referenced, but there seems no connection between.

hey guys i am newbie to the unreal engine. most likely with unity.
and i just found out something weird. Have a look

this is the spline in content example.
when i move the transform in map, it actually update the transform valuable in it.
and there seems no connection, referencing between them.
any comments would be really helpful.
just hope it just look weird only by me, missing something simple
cheers.

the location is likely in local space. beyond that you need to explain your issue in a manner people can understand.

You are manipulating the 3d widget of the start transform variable. You can check the detail in the bp detail panel.
