Inconsistency in filtering processes

Question

Please take a look at the 4 screenshots below:

CPU Usage reacts correctly to a change in the filtering field, while Processes and Physical Usage show the same, i.e. the same as without the use of filtering.
It would be good and practical if the values displayed in the status bar could be the sums of the values from the displayed processes.

Best regards
and wish you a quick and simple change :)
