Why don't my repos automatically fetch changes?

[dsmoore1600]

I have been using source tree for many years, and for the most part have always enjoyed it. I started using it about a year ago at my current job, and the auto fetch hasn't worked since. I am almost certain it is some sort of security setting on my machine, but I don't know what to look for. I am using Version 3.2.6. The following image is of my Repo Settings, so I know I at least have it set to do the fetch automatically.
