When Searching for "CPU" i get all Items. No problem.

When searching for an item named "sendmessage_to_cp" f.ex. i receive nothing.

When searching for an item named "sendmessage_to_cp" AND i select a hostname, i get what i want.

Same if i search for the name AND application string, i receive the wanted Items.

Searching with all hostgroups and the String -> nothing

PHP fpm and httpd already restarted.

Loglines (when searching only for the "sendmessage_to_cp" string:
