Strange behavior with detect internet.

Hi all,
while I was checking all connections I have noticed something strange happening on the main router, running RouterOS v6.46.6.
I have 2 WANs: WAN1 is the main connection (active default route with distance 1), while WAN2 is waiting with distance 2.
WAN1 is 192.168.1.2/30 and WAN2 192.168.0.2/30; WAN1 is a point-to-point ethernet connection, no DHCP, nothing else there.

Internet detect was detecting WAN1 as Internet and WAN2 as WAN, as expected.
To do some test, I have disabled WAN1 so WAN2 was detected as Internet.
When I restored WAN1, both WANs were detected as Internet.

At this point I have noticed several connections with an IP of 192.168.1.110 for the internet detection; however such IP does not exist anywhere in that subnet.
So it seems to me that something went wrong somewhere in the router that “created” such IP ???
However after that I disabled detect Internet, restarted it and it worked fine by having the communication between 192.168.1.1 and 192.168.1.2 when detecting internet by querying the MikroTik server on port 30000. Below the screenshot visible from Torch about this situation.
