Wyse 5040 Pulling Incorrect RDP Session Settings

We have suddenly ran into an issue where our thinclients are pulling the RDP Session settings of other devices. We have a group policy that defines general config (power, sleep, ENET0, etc) and we create an exception at the device level to add the RDP connection settings, including the username\password. All of a sudden, thinclients will start an RDP session with credentials that are set up on a different device (i.e. thinclient A is no longer using it's user A credentials and is now using user B's credentials which was setup as an exception in the RDP session settings for thinclient B.

I've also seen thinclients suddenly change their hostname, causing there to be multiples of the same hostname listed in WMS. We are using WMS version 3.2.1.44

We have a default parent policy and then below that we have to child policies (one for each geographic region). Only one of the child policies is having this issue.. So we created a new child policy with the default parent policy and we still have this issue. It appears if we factory reset the thinclient and join it back, it will work correctly for a little bit.. But after a random amount of time (30mins or an hour.. sometimes longer) we start seeing the same issues again.
