Hi,

You should not use :normal! <CR> but rather :normal <CR>. The different
is that :normal! does not take any user specific maps, and since in
normal mode <CR> is just a jump to next line, it will just go to the
beginning of next line. This also applies to your manual test. It just
should be
:normal <CR>
without the bang. See ':help :normal'.

I hope it helps,
Marcin
