Google calendar not syncing right with Calendar on phone

I have been successfully syncing multiple Google calendars on my iPhone 4S for the past month or so since I got it, but last week it started acting funny and will only let me edit the calendars from my main account and has all of my other calendars as an invitation, as shown in the picture.

I have my calendars set up through Exchange and using m.google.com/sync/settings/iconfig/ and I have deleted and reinstalled the Exchange account, and reset everything multiple times, but it still keeps doing this.
