Thanks for taking the time to report this bug.
This bug report isn't very useful because it doesn't describe the bug well. If you have time and can still reproduce the bug, please read http://bugzilla.gnome.org/bug-HOWTO.html and add a more useful description to this bug.

So. GNOME Software offers to create GNOME Shell’s “applications folders”, to let you group applications in the Grid of applications. When you have two applications you want to group that way:
* you go in the “Installed” view of applications;
* you click on the “Selection” ([✔]) button; you select your two applications; you click “Add to folder…”;
* you have a modal window that appears, with a list of existing groups, and a « + » item.
If you want to group your two applications under a new group, you hit this « + » item, have a little popup, enter the name of the new group, and validate.

For now, the new group is added to the list of groups. You have to select it (it shows it is checked with a « ✔ » mark), then to confirm you really want to add the two applications you want to group to the selected group you just created. At least the first of this two actions is unnecessary; in fact, the second one is also unuseful.

Because if you selected two applications for grouping them, and then created a new group, we could assume it is for grouping the two applications in this new group. The two popups should so be closed when the user validates the name of the new group; or, it could have to confirm he wants to add the two applications  to it, but the group newly created should be automatically selected, assuming it’s the most common case.

app folders: Select newly created folders

This is the expected behavior.

Untested, but looks sane to me.

I agree with the reporter. Renaming for clarity.
