User randomly wiped - Yale Assure SL, Device page, Lock Code Manager

I set up four users using the Device page.
User one is in position 1 and is shown in Device page and LCM.
User two is in position 2 and is shown in Device page and LCM.
User three was in position 3, but now code and name are null
User four is in position 4, but had to be re-added as it too had previously been wiped (code and name were null).

Position 3 and 4 seem to be where the issue is. I get user 4 to show up and user 3 goes null. I get user 3 to show, but user 4 goes null.

Very odd behavior.

Anyone else seeing anything like this?
