The removals news items for owncloud differ from the PTS:

https://packages.qa.debian.org/o/owncloud.html

[2017-05-06] Removed 7.0.4+dfsg-4~deb8u4 from stable (None)
[2016-04-26] Removed 7.0.13~dfsg-1 from unstable (None)
[2016-04-15] owncloud REMOVED from testing (Britney)

https://tracker.debian.org/pkg/owncloud

[2016-04-26] Removed 7.0.13~dfsg-1 from unstable (Debian FTP Masters)
[2016-04-26] Removed 7.0.13~dfsg-1 from unstable (Debian FTP Masters)
[2016-04-15] owncloud REMOVED from testing (Debian testing watch)

The tracker data appears to have duplicated the removal from unstable
and dropped the removal from stable.

Hi,

The duplicate entry is unrelated to the removal of the version from
stable. The duplicate entry has been created right from the start.
Possibly because ftpmaster was sending the mail to the package tracker
twice, through two different channels. This is likely fixed nowadays,
it mails only @packages.d.o.

As for the lack of the news about the removal from stable, it's not clear
why it's missing. I don't see any reason for the code to skip the message
so it likely did not receive it altogether.

Maybe for a reason similar to #792600. I don't think there's much
actionable in this report.

Cheers,

Maybe delete the duplicate and copy the missing mail from the PTS.
