Search in user collection from tag page malfunctions

For example: tag page "Architectuur Nederland" shows me as using that tag 71 times. However if I click that number nothing comes up, because it actually looks for "Architectuur Nederland" as such in my collections - but not "Dutch Architecture" which is the tag I'm actually using and which is combined into it.

So, on tag page:
http://www.librarything.com/tag/Architectuur%20Nederland

You click "You use: Dutch Architecture (77)"

And it takes you to
http://www.librarything.com/catalog/BarkingMatt&tag=Dutch+Architecture

And that works!

What am I missing?

Yes, either this is fixed, or it's because the main tag is now "Dutch Architecture" instead of "Architectuur Nederland". (Remember?: this was one used as an example when you changed how the main form of a tag title should be calculated).

I was experiencing this problem on several tag pages back then. No longer. So I think this is fixed. Closing, will report again if I even see a fresh example. Hope not.
