If you uploaded a resume into Word Online, it has everything on top of itself instead of spreading out, you must know that the templates have been designed for Microsoft Word only compatible with Windows and MacOSX, and for Apple Pages, only compatible with MacOSX, they are not compatible with Microsoft Word online version.
I recommend you download a trial version. You can download Office 365 for a free trial (1 month) here: products.office.com/en-us/try
Good lucky!
