All hosts in the group are not shown with the Host groups filter in Latest data

[Markku]

I have an interesting observation. This is from my own 8.0.0, but I've recently noticed similar issue in other places as well, they have been quite recent 7.0.x versions.

• If I look at the Host groups, I see 32 hosts in the Linux servers group. This is correct.
• If I go to the Latest data, reset the filter and only select the Linux servers group in the Host groups filter, I get only 17 hosts in the Hosts subfilter section (and in the data table as well). Why are 15 hosts missing?

However, if I enter for example "memory" in the Name filter, now I see all 32 hosts listed in the Hosts subfilter section (and in the data table as well). In this example, the word "memory" will correctly match all hosts in the group as (in this setup) they all have memory-related items configured or discovered.

I am not able to reproduce this in any artificially created set of hosts.

Any thoughts? Can there be some caching somewhere that needs to be rebuilt, or something like that?

This is not a permission-related issue as I'm using the super admin here, and I don't see any practical differences between the hosts that are always shown and the ones that appear only later in the search tests. Whether a host is enabled or not does not seem to affect either (I see both enabled and disabled hosts in both groups of devices).
