Plesk 8.4.0

[raakh]

I upgraded my Plesk from 8.3 to 8.4.0 via SSH. Now all the packages updated except Spam Filter that have yellow sign to update it. I tried from Plesk as well as from SSH command prompt to update but nothing is changed and still the same position.

The update says at the end:
The following packages you requested are already updated:
perl-Text-Iconv
The packages were installed successfully.

Kindly advice what should I do?

Thanks & best regards
