Rollback of impairment does not generate reversing accounting entry

In our test environment, we are testing Capital Projects. I have done an impairment on an asset linked to a capital project.

This works fine and generate the correct accounting entry.

Now I have processed additional costs on the Capital Project.

These cost adjustments can only be processed when the impairment is rolled back.

I expect the rollback to generate the reversing accounting entry, however this does not happen.

Is this expected behaviour? Or there an extra setup step needed?

Tips are welcome
