Select interface for Netflow don't working

RouterOS General

Hello!

I’m using Mikrotik x86 6.48.3

I’m trying to setup netflow reporting using Manageengine Netflow Analyzer. In Traffic Flow general settings I select only one interface (LAN).
But in Netflow Analyzer console I see two interfaces (LAN and WAN). My Netflow setup on Mikrotik side is very simple - enable netflow, select interface, and set collectr IP.
