Quick controls wiped from inspector

Has this happened to you? …

After working on a project with lots of quick control settings in the inspector in the project window, open or start a second project.
Finish working on the second project and close it.
Go back to the first project … All quick control settings wiped.

This only seemed to happen on midi channels. The VST instrument quick controls were still there.

Is this a known issue. I had to reload all the individual track presets.

Thanks in advance for any replies.
