Software update notification

Hi

I noticed that "Software update notification" had been added to LMS and have had it enabled and recieved update notifications with it on my server.
However today I notice that there is a new "Nightly" version available for my main server but it has not informed me in the webgui.
I checked my other server (A Cubietruck) and it did indeed have an update notification.

Main server:
Logitech Media Server Version: 7.9.0 - 1441262387 @ Sun Sep 13 04:00:58 UTC 2015
(Latest version is logitechmediaserver7.9.0-0.1.1442408783.noarch.rpm)
Operating system: Red Hat - EN - utf8
Platform Architecture: x86_64-linux
Perl Version: 5.16.3 - x86_64-linux-thread-multi
Audio::Scan: 0.95
Database Version: DBD::SQLite 1.34_01 (sqlite 3.7.7.1)

Installed via RPM (yum) and running on Centos 7


Cubietruck Server:
Logitech Media Server Version: 7.9.0 - 1441262387 @ Thu Sep 3 07:14:54 UTC 2015
Hostname: Cubietruck
Operating system: Debian - EN - utf8 Platform Architecture: armv7l-linux
Perl Version: 5.14.2 - arm-linux-gnueabihf-thread-multi-64int
Audio::Scan: 0.95
Database Version: DBD::SQLite 1.34_01 (sqlite 3.7.7.1)

Installed from .deb (apt) and running on CubianX (Debian)

Webgui informs me:-
A new version of Logitech Media Server is available (7.9.0 - 1442408783).

Is this a known fault or does the system wait a specified time before informing the user ?
