Avatar not displaying properly on dashboard beside commits

The standard non avatar is displayed instead of my own beside my commits in the dashboard view. (example below)

The email I am using per commit is correctly tied to one of the emails on my Github account. The commits are correctly tied to my account.

The email address I had been using does contain capital letters so I decided to test and remove them and it does fix this issue. Even though the email address saved to Github does contain the same capital letters. I feel like this is a bug.

See below: The bottom commit doesn’t have my avatar. But, the top one does (no capitals in email).

Avatar is displayed properly everywhere else except dashboard.
