Hello,
That would usually indicate that the operational DB [MySQL] is not synced with the Sphinx instance, or instances.
Start by checking the entry status in the DB with:
mysql> select status from kaltura.entry where id='0_nh8lh82p';
For an entry in status ready, the value should be 2.
If it is indeed 2 and you do not see it in KMC, try reindexing the entries. You can do so by running:
# /opt/kaltura/bin/kaltura-sphinx-reindex.sh
