Strange behavior with filtering items

[demolator]

Hello all,

I have a very strange behaviour filtering discovered items (Monitoring -> Latest Data)
If I filter items by name, I have one item less than if I Filter by name and host.

Filtering by name only (5 Items, "pull_mind" missing):



Filtering by name AND host (6 Items, includes "pull_mind"):



Does anybody know where to start to debug this? Or did I miss anything?

The SQL records look exactly the same:

zabbix=# select * from items where itemid in (33584, 33585);
