All the effect controlls are gone
I got a project file in which all the clips have no effect controls except for time remapping - the rest is gone.
This is what I see:

This is what I should see:

What I tried:
- copypaste the files from the seqience into a new one.
- copypaste all the timeline elements into a new project
- reset the workspaces, switch between the workspaces
- reset Premiere Pro Settings
- clear all the cache files both manually and in the Preferences -> Media Cache
- open this project file on different machines (Mac\PC) and different versions of Premiere Pro.
The only way to fix it so far is manual clip-by-clip replacement of everything that lies on the timeline - new clips placed do have all the effect controls. The problem is - this is only part of a bigger project and the whole project has hundreds of clips, so manual work will take ages...
Here's the partly project:

Any ideas of what happened and how to fix it at the lowest possible cost?
