@xuedaolao - Sorry for the trouble with this! We do test each release, and despite our best efforts there are inevitably some bugs that slip through. This is typically the case with all software releases, including ones by big companies such as Apple. We strive to do our best with the resources we have available, and hope that the changes we make to the site have a positive impact on membership, thereby allowing us to do even more for our members.
This issue has been added to our list and we hope to have it fixed soon!
