After cutting a tree the new generated object (the cutted tree) was a different kind of tree instead of spruce tree it turned into the more branched tree.

Not sure what you mean, all the trees keep a similar shape when being cut down, some changes as branches fall off and are collected as sticks, but otherwise I'm not sure exactly what you're talking about. If you could provide a screenshot, either by linking an image via a post in Discord, or an image hosting site that would be great.
