Mapbox Base Layers not showing correctly

I attached two images, one for the openlayers settings and one for the mapbox layers setting.

I also have this issue:

"Not suggested compatible version. Though you are very welcome to use whatever version of the OpenLayers library you want, it is suggested that you use version 2.12. You are currently not using that version or we are unable to determine which version you are using. Update your library settings at OpenLayers settings."

Even though the external library is pointing to the correct 2.12 version.

Thanks for your help.

weird, other maps work, only the mapbox maps have an issue with being misaligned.

tried changing the layer to be xyz and using the following base urls:

//a.tiles.mapbox.com/v1/mapbox.world-black/${z}/${x}/${y}.png
//b.tiles.mapbox.com/v1/mapbox.world-black/${z}/${x}/${y}.png
//c.tiles.mapbox.com/v1/mapbox.world-black/${z}/${x}/${y}.png
//d.tiles.mapbox.com/v1/mapbox.world-black/${z}/${x}/${y}.png

The map tiles shows but is still off on the Y axis

tried removing the module files, clearing cache and reinstalling, but all the mapbox baselayers are still not showing correctly.

it did seem to fix the issue with detecting the 2.12 release

Anyone have any idea whats going on?

This is what exported for MapBox World Black

$openlayers_layers = new stdClass();
$openlayers_layers->disabled = FALSE; /* Edit this to true to make a default openlayers_layers disabled initially */
$openlayers_layers->api_version = 1;
$openlayers_layers->name = 'mapbox_world_black';
$openlayers_layers->title = 'MapBox World Black';
$openlayers_layers->description = 'MapBox World Black';
$openlayers_layers->data = array(

  ),
  'projection' => array(
    0 => 'EPSG:3857',
  ),
);

no, i disabled the module cause it was causing an error starting with beta4.

i disabled and removed the mapbox module.

i get this when i try to edit a map

Exception: Projection 900913 lacks an authority code. Read http://drupal.org/node/1944074 for hints. in openlayers_get_projection_by_identifier() (line 996 of /home/s4bf8be4935233c1/www/sites/default/modules/openlayers/openlayers.module).

thanks for your help, i think i fixed it.

had to disable module --> uninstall --> clear cache --> reinstall

the mapbox maps seem to work now (although it still seems to pull broken image tiles but since i lock the map, the broken image tiles don't bother me)

attached is a screenshot
