Quick links is a feature of gmail. I believe it was introduced as a lab. It allows you to create bookmarks or favourites from the labels you use most.
Look up (Google) "Gmail quick links", and you will find information.
When you use nested labels with gmail, it has the appearance of folders although technically they are not folders.
I don't know ... but off the top of my head I could think of two possibilities.
Maybe the code for Gmail in your browser's cache got corrupted. Try
clearing its cache and cookies. It has been known to fix quite a
number of odd problems.
Or maybe Gmail changed something about the URL to get to that nested
label/folder, so that the previous URL doesn't bring you there anymore
and the top-level label was the only one it could get to. You might
need to save another Quick Link to the "Kathy" label.
These are only guesses.
The Quick Links feature is only a Lab, which means it is subject to
changes, bugs, etc. You might have hit one of them.

Hmm, I haven't been using Quick Links for the purpose you did, but I
just tried adding one for a sub-label. It worked for me!
But I am still (and hopefully forever!) using Gmail's "old" look.

Gmail still supports sub-labels (sub-folders), of course.
But maybe something broke in the Quick Links implementation. As I
said, it is a Gmail Lab so it is not fully supported and oddities can
happen. If so, with luck it will be fixed, if people like you give
them feedback. (Hint: This email forum is not feedback to anyone at
Google.)
