PHP notice when activating custom field types

I made a couple of custom field types as plugins including https://github.com/scottsawyer/cmb2-field-address. However, when I activate the plugins, I receive php notices:

PHP Warning: include_once(/public/wp-content/plugins/cmb2/includes/CMB2_Field_Address.php): failed to open stream: No such file or directory in /public/wp-content/plugins/cmb2/includes/helper-functions.php on line 44

PHP Warning: include_once(): Failed opening ‘/public/wp-content/plugins/cmb2/includes/CMB2_Field_Address.php’ for inclusion (include_path=’.:/usr/share/php’) in /public/wp-content/plugins/cmb2/includes/helper-functions.php on line 44

Plugin ‘cmb2-field-address’ activated.

As you can see, CMB2 recognizes the new field type, but the helper function is attempting to load the plugin file from the CMB2 plugin directory. It also appears it’s capitalizing the plugin name ( maybe because the plugin class name? ).

The plugin activates, the field seems to work, so this is not a show stopper, but I’d love to clear this up.
