The problem here is that your blocks are not correctly specified. If you
run M-x org-lint on your example, it will tell you the blocks may not be
correctly specified. You need to tell org what sort of block it is. Org
supports a number of different block types, such as source code blocks
(#+begin_src/#+end_src), example blocks (#+begin_example/#+end_example),
centred blocks (#+begin_center/#+end_center) etc. You can use C-c C-, to
run the command org-insert-structured-template to select the block type.
If you first highlight the region, it will be wrapped in the block you
select.
