Dualshock 4 RT and LT triggered once on load for HLDX build

I noticed a weird interaction when building my project on Windows for HashLink with the -lib hldx DirectX library and using a Dualshock 4 gamepad.
As soon as the project loads up, both the RT and LT buttons of my gamepad are triggered once.
This does not happen if I build for OpenGL (-lib hlsdl) and it does not happen for either library if I use an Xbox 360 gamepad.

Is this a bug, or does anyone know anything about this? It isn’t necessarily a huge issue, but it could make “press any button to begin” screens difficult if that’s what your game opens up to, and just seems like something that shouldn’t happen.

Thank you for any info!
