Samsung Galaxy Tab 4 not getting 5.0.2 update

I am working on provisioning several (3) Samsung Galaxy Tab 4's Model SM-T530, and one of them is not getting the latest system updates. It is stuck at Android 4.4.2, Kernel version 3.4.0-3235464. I have tried manually running the Update now, verified I am online, all that fun stuff. This is the WiFi Only version, so it is not dependent on the carrier releasing the update, and the other two that were purchased from the same vendor at the same time, updated just like they were supposed to, and are now at 5.0.2. What can i do to troubleshoot this issue? (Logs, check settings, etc)
