Can't find the paint / raise / lower terrain setting in unity 2018.3

Hi!
I’m trying to make a terrain but the problem is that I can’t find the paint / raise / lower terrain setting in unity (which the version is 2018.3). What I expect is this:129743-screenshot-6.png

But what I got was this:
129744-screenshot-9.png

Is there something wrong during unity installation?

P.S. Thanks

These options can now be found under the Paint Terrain tool:
