Difference between Application and Application details

Hello, AdvantNet!

I can't understand one trouble: I see one traffic value for some protocol in Application tab and other (lesser) value if I click 'View details'.

For example (Application Tab):
pop3s 161.61 MB 67%
http 28.87 MB 12%
microsoft-ds 28.49 MB 12%

And if I clicks on 'http':
Source IP Destination IP Application Port Protocol Traffic(14.91 MB) % of Traffic
x.x.x.x x.x.x.x http 80 TCP 14.16 MB 95%
x.x.x.x x.x.x.x http 80 TCP 384.56 KB 3%
192.168.7.202 192.168.77.1 http 8080 TCP 299.19 KB 2%
192.168.7.200 192.168.77.1 http 8080 TCP 52.25 KB <1%
x.x.x.x 192.168.77.79 http 80 TCP 11.63 KB <1%
192.168.7.4 192.168.77.76 http 80 TCP 4.89 KB <1%

Look at the 'Traffic(14.91 MB)'. It's very different to 'http 28.87 MB 12%' !
And I have this behavior for most entries.

NOTE: In TroubleShoot page all data are correct, but it's difficult to use TroubleShoot everytime instead of Application Details.

Thanks,
Sergey
