In my vimrc I have

nnoremap <Leader>h :bp<CR>
nnoremap <Leader>l :bn<CR>

But I have to source my vimrc to enable them with (:so $MYVIMRC). If I do a :map after starting vim I will see all my other shortcuts map with leader but not this one.

Their also so no other shortcut map to <Leader>h.

How this can happen?

I have the same problem with let @+=join([expand('%'), line(".")], ':')

    Your plugin might have unmapped. If your vimrc has the mapping and not overridden by plugin, it would have been shown. Which character you use for leader?

    You have defined mapleader after these mappings. The default leader is a `. So do \h` and \l work? Jun 29, 2016 at 18:22

    Run :verbose map <Leader>h to see what messed it up. Jun 29, 2016 at 18:42

From :h mapleader:

Note that the value of "mapleader" is used at the moment the mapping is defined. Changing "mapleader" after that has no effect for already defined mappings.

Your mapleader is changed after your mappings in question. Meaning your mappings will use the the default mapleader of a \. e.g. Your mappings will be \h and \l. Simply define your mapleader before all your mappings to get the effect you desire.
