I cannot push to master after VS Update

Hello, I am fairly new to Git and Github. I have come across a problem when trying to push to master. I can commit just fine, but when I try to sync (I am using the Github desktop app btw), the push always fails for some odd reason. I tried opening the shell and using git status but it always tells me that I am one commit ahead of the master branch.

This problem only showed up until I accidentally updated VS to Community Update 3, it did cause some issue with the project, like having to clean the old build. But now I can’t seem to figure out why it wont let me push. Is there something in VS that needs to be fixed? Do I need to update the gitignore, which is currently:

*.sdf
*.suo
*.sln

/Binaries
/DerivedDataCache
/Intermediate
/Saved

Is there a git command that can fix this issue that I don’t know about? Any help would be appreciated.
