Filter has bugs

[koftnt]

I added some simple rules to Filter. Please note that the filter with code = 3 in the following picture

First I select it to do filter.It works fine and gives me the issues with code = 3
After several random clicking different filter rules via web UI. I reselected the code=3 filler .It is frustrated to me that the filter result is empty . The reason is the filter query has a unnecessary feature(statuses:do_not_care)。It is weird for same filter has different results
