Flattened track has two separate mixer/volume automations

[StickPlayer]

The track was originally a short midi sequence. This was then frozen and flattened.
I'd post an image if there was some way to add it to this, but all I can find is image URL, which an image on my desktop can't be referenced by.

That said, why is this forum basically technology from 2000?

Okay, so, ire aside: The MIDI track included mixer/volume automation. After flattening, that automation line appears as a solid dark-gray line. A dashed red line also appears, which is definitely the current volume setting on the track. I can move the track volume and see this line correspond.

However, I can't edit the automation curve on the red line. Any attempt actually modifies that grey solid line - it responds exactly as I want the REAL automation line. And this makes very little sense to me - it isn't ACTIVE. It does NOTHING once flattened. Why would anybody want to change settings that won't matter? And why would you NOT want to be able to automate volume after flattening?

To be clear: The grey line responds to user changing automation by doing what I expect the red line to do - it gets automation handles, and I can move them around. But of course, the whole automation is disabled and does nothing, while the enabled level can't be automated.

This is really weird to me, and doesn't seems to have any purpose insofar as serving the user goes.
