Unexpected behaviour of query filters and dashboard filters

Hi all,

Unfortunately i have experienced the filter in the query doesn't limit the data can be view from the same query in the dashboard.. For example the follow query is filtered with ticket created data from the last month:

and in the kpi dashboard is the same until the date filter is identical (ticket created data from the last month):

But if i expand the range date in the dashboard the kpi data is update with the new date selection, even if the date in the query filter is still filtered with ticket created data from the last month:

Why do i have managed filter at the query level if in the dashboard they can be override?

Another example: at the query level i could apply this filters:

in the dashboard i can filter the group and it gives to me a nonsense result like this:

because none of this ticket have the "Second level" group as assignee.

But if, at the query level, i apply this kind of filters (excluded) in other hand:

in the dashboard i can filter the group, again, and it gives to me this result:

that are, in this case, the ticket that are assignee to the "Second level" group and i don't want to show in the result of the query and don't want to show in the result of the dashboard..

Please could you help me to understand the filters interaction between the query level and the dashboard level?
