the global title settings were not available to add to a feature, however I was able to add the data to the feature manually.
This needs to be fixed but here is my workaround:
- Generate the feature
- untar feautre
- Open feature.info file in yourr fav text editor
- add the bellow line to the file:
features[metatag_config] = "global"
- update the feature via drush fu FEATURE_NAME
- It's there
