1. Navigate to web scenarios;
1. in the filter set multiple hosts, so that "Host" column is visible;
2. open web scenario in form;
3. delete the web scenario;

Result:
Observe that "Host" column is missing, but filter still shows two selected hosts.
Pressing "Apply" again in filter, again the "Host" column is visible.

Expected:
Either "Host" column is always visible just like some other sections, or visible when two or more hosts are selected in filter regardless of performed actions like deleting a web scenario.
