Show Keyframes in Submixes Broken in Premiere Beta 23.6

Hello,

It appears that the function to show different keyframe types is broken in the Premiere 23.6 (build 46) beta on an Apple Silicon Mac running Ventura. I cannot switch between different keyframe types to control automation in submixes in my timeline (i.e. cannot switch between balance, mute and volume.) This functionality works fine for regular audio tracks by right clicking on the automation line and choosing the desired property.

This function also works in the last official release for Premiere Pro 2023. 

I was able to reproduce this problem creating fresh projects in Premiere 23.6 (build 46). I have attached a screenshot of the menu that is not functional.

Thank you for reading this.
