Auditbeat 'process.title' gone

Before deploying in production, I've made a demo deployment of elk and used auditbeat (7.8.0) to log actions on the system. In kibana, I was able to put it into a dashboard with using the process.title field.

I've now deployed everything in production on the latest version (7.9.0) but now process.title doesn't seem to exist. Closest I could find is process.args but it's much less clean.

Is there a way to get the process.title field back? Thanks ahead.
