WDS Issue, Flint 2 (main), Slate AX (WDS)

I am running the latest released firmware for the Flint 2 and Slate AX. The Flint 2 is hooked up as my primary, and the Slate AX is used for rebroadcasting via WDS and also extending the network to a network switch. For some reason after the latest firmware update the Slate AX can no longer connect to the Flint 2 via WDS, but it can enter Extender mode, unfortunately the devices are no longer in the same subnet if i use Extender mode. Additionally I keep having to do a clean uboot wipe on the Slate AX just to get new firmware on / access the UI if i set it to WDS mode.
