Game Starting on Second Monitor

I'm having an issue with the game opening on my secondary monitor rather than the primary.

Info:

• Game Version: 2.0.6f2
• OS: Ubuntu 18.10
• Platform: i5-3750k, 16GB RAM, RX 580 (Mesa 19)

I've tried using the in-game monitor settings, however upon reopening the game 'Select Monitor' is always reset to 0. I've also switched to windowed mode while testing, same issue with Select Monitor resetting to 0.

The game is running great otherwise.

Here is the only relevant portion of the log I can see:
