How can i add a block below the content of a node? I created many blocks and used them in my nodes regarding to contet types.

But i need another thing.
I created new block.
In the "/admin/structure/block" page i dragged this block to "Content" region.
The block appeared in content region. But it appeared above the node body.

In content part of "/admin/structure/block" there is 2 blocks:
"Main page content" and "My own block".
My own block is below the other block. But still it appears above the content body.
Should i pay attention any other thing?
Thank you.
In the Block UI at admin/structure/block toggle "Show Row Heights"



Set the weights manually to ensure they are correct.
