Can't find default stream when rebasing development stream

When I go to rebase my development stream with the latest baseline, the current integration stream does not automatically show up. Instead I get a list of all the available streams. When I select the integration stream from the list, I get the following error:

Because this stream has no default stream from which to retrieve recommended baselines, the baseline list has been seeded with the stream's current foundation baselines.

To proceed, you'll need to edit the baseline list directly. (Click 'Advanced' to view/edit the baseline list.)

When I go to Project Explorer, and look at recommended baselines, everything shows up correctly.

This had been working correctly historically. What can I do to set the default stream back to the integration stream?

I didn't saw that error message before, but a workaround would be to:

• rename the current child stream (which no longer has the right default parent),

• make an new child stream from the integration stream, and rebasing it with the right baseline from its default parent (the integration stream),

• make the first child stream (the one with the issue) obsolete,

• go on from there.
