When I write:
#Head1
##Head2
###Head3
####Head4
The first three headers are successfully displayed in the pdf output.
But for the ###Head4, it cannot separate with the next line, the next line sentence just starts at the end of the head, not automatically start a new line.
I tried to add a double space after the Head4, it still failed.
I also tried to add a blank line after Head4, but it still failed!
Could anyone help me to deal with this issue? Thanks a lot!!!!
