Cannot remove desktop files from .config/autostart folder

I am configuring a arch based machine with a minimal desktop setup. I am logging into a qtile session, and I have the 'lxsession' package installed and run on start, but I am not logged into an lxde session. My problem is that I have some desktop files that keep appearing in ~/.config/autostart and I do not understand why. There is no autostart folder in ~/.config/lxsessions, there is no /etc/xdg/LXDE folder and nothing related to autostart in /usr/share/lxsessions. I keep deleting the .config/autostart folder contents, everything is disabled on the lxsession gui setting app for autostart, but on each reboot the desktop files are back. Does anyone have an idea of why that could be ?
