Trouble w/ Tartarus v2 Keymaps in Terraria 1.4

I just bought and setup my Tartarus v2. I initially modified the first keymap and could not get the changes to work in Terraria, so I created a second keymap. When I start the game the second light is lit, but by the time the game loads all the way and I actually get to a world it changes back to the first light by itself. If I tab back to Synapse the second light relights and if I tab back to Terraria the second keymap stays active for a couple of seconds. During this brief period, the keymap changes function. Alas, the first light changes on its own again and the default keymap is reactivated. It does not matter how many keys I remap in that default profile the default keymap layout remains the only keys that are pressed. This is quite frustrating.



During my initial search, I came across a lot of videos and posts about keyboards having troubles with 1.4 when it came out. I never noticed these problems, but I did try some of the workarounds they came up with. I have the game set to run as admin, I restarted my computer, I tabbed away and back (this is how I figured out it was switching the keymaps on its own), and I brought up the Task Manager via ctrl-alt-del. I am on Windows 10 Pro 64-bit that is up to date. The game is on Steam and both are up to date. My drivers are up to date. I have not had a chance to try it with other games yet.
