Hi,
is your map tiled? It seems to be your icon is pretty large, and if it
crosses the tile borders,
it simply won't be displayed as there is no guarantee the other half of it
will be painted
in the nearby tile because of conflict resolution.
If you don't care about conflict resolution, you can turn it off and allow
partial labels (a
feature appeared in 2.6.x I believe):

Cheers
