Changing default settings in blank projects causes permanent change to all projects

changing default settings in blank projects causes permanent change to all projects

steps to reproduce
install ue4.17
create new blank project no content desktop with high quality
name it anything
create folder in content and name it
click edit bp_skysphere
double click any of default curve equations
menu save as and save in content/folder I just created
close project and select save all
delete project in epic games launcher
start new project same settings as before

it seems as though instead of having a new copy of the bp_sky_sphere placed into the project it is just using the default copy in the engine any edits are being saved in the default. The project should really have its own copy of skysphere as this could cause a lot of errors especially when moving stuff in folders. This is the first thing I would want to do.

p.s. is there a way to repair the default folders I could do with that right about now.
