PROS always showing welcome message

[MatthiasPortzel]

Whenever I open a new window in Atom, I'm greeted with the PROS welcome screen, complete with an unchecked box next to the "Show Welcome for PROS when opening Atom." Toggling that box, uninstalling and reinstalling pros, and re-opening Atom have all failed at fixing this on-going issue.
If a fix for this issue is not forthcoming, I'd be satisfied with a workaround to stop the window from showing up.
MacOS 10.13.3; Atom 1.25.0; PROS CLI: 2.6.1 - Package: 0.7.4

I did some digging. The message is being opened by this line of code, which indeed ignores the check box setting. It appears to be running in a child process which pros which fails for some reason when the window is first opening on my system. The same check succeeds when I run it from the console inside of Atom, and pros is actually installed and updated on my path.
