How to restore default Basic Place Actors?

I was playing with New Modeling tool.
Brough the default sphere did some sculpting…and save
Now the sphere in all other projects has changed to my sculpted sphere!!!
I tried verify in launcher but didn’t do anything.
I also tried to delete it from engine and replace it with another static mesh and still not getting it back.

Basically need to restore the sphere without reinstalling the whole thing!
