Yeah, it seems that the N900XXUDNA6 is not for the US Variant
"N900XXUDNA6 Android 4.4.2 KitKat official firmware update for Galaxy Note 3 SM-N900 is now rolled out by Samsung. This is the first KitKat official firmware for Galaxy Note 3 SM-N900. The firmware update rolled out in various countries including Sri Lanka, Nepal, Indonesia, Singapore, Vietnam, Kazakhstan, Ukraine, Russia, Thailand and India"
The DNA6 would be for the SM-N900 Exynos CPU devices, not the SM-N900A Snapdragon. That is probably your problem (In addition to trying to roll back to JB from KK)
Unfortunately, I dont know of any stock KitKat firmware. There is MI9 on Samfirmware
's site, but that is JB not KitKat
