Flowview not taking account of the filter src/dst IP

On flowview 5.0 I try to setup a filter to have just whats is originated from an ip range (10.0.2.0/24).

But when I go to the tab flowview and setup that filter, it's absolutely not taking in account.
IO activate the debug of flowview plugin and all flowview file, but I don't get any error.

I just get the whole flowview record sorted by Byte.

Any clue how to have more info on whats going on ?
