I have created a basic segment to show this unexpected behavior.

When I apply the segment as shown in above image, I expect to see 5 visits in Visitor Log. But, when the segment is applied, there are only 3 visitors in Visitor Log as shown in the image below.

I have observed this behavior in more complex segments, but I can reproduce it in basic segments when I use the options Action URL or Page URL.

I'm doing something wrong or this is really a bug!? I'm using Matomo 3.7.0, but this occurs in release 3.5.1 too.

Best regards.
