Xcode Main.storyboard not showing what appears in the iOS simulator

I am working on a project with other teammates so we have be storing our project on the cloud as a zip file. After unzipping the file, Xcode does not display the main.storyboard correctly; won't show buttons, labels, images, etc. However, when built using the simulator, all of these display correctly. In Xcode I can access them and change them but am unable to delete or move them through the main.storyboard. Any ideas or suggestions to fix this inconvenience?
