Why does the Personal Project Store page under Tools | Options display a different list of projects to those listed in the the File | Open list (when filtered to show personal projects)?
The Personal Project Store page shows all projects in your local database. This includes personal projects and any shared projects you may have saved locally. In comparison to this, the File | Open list (when filtered to show personal projects) shows only personal projects, i.e. those that have not yet been shared. The list of projects listed by these options will therefore be different.
