That's not necessarily strange. Patent applications aren't necessarily published as soon as they are submitted. Rules vary a bit depending on where the application has been filed which can be in multiple places so am not sure where and when this particular application has been submitted or when it will be made public.

"Patent applications are generally published 18 months after the earliest priority date of the application. Prior to that publication the application is confidential to the patent office. After publication, depending upon local rules, certain parts of the application file may remain confidential, but it is common for all communications between an Applicant (or his agent) and the patent office to be publicly available."
