Yay! That solved it. I have the latest version now from Github.
Thanks @elliot!
I do have the latest versions:
ACF Version 4.3.4
ACF Repeater Field Version 1.1.1
Wordpress Version 3.8.1
I replicated my setup and I think I found the issue. I actually have conditional logic in the tabs that triggers from the checkbox field above. It is somehow affecting the whole issue.

Thanks for the response @matiasvad
However, I’ve tested this on both Chrome and Firefox but the issue still persists.

If you notice in the video, the custom fields are located in the User’s profile. I don’t know if it is related to the issue.
