Device showing loop problem

Hi… I m new to Mikrotik…I have a seen a problem in LHG5 that it shows "wlan1: bridge port recieved packet with own address as source address (6c:3b:6b:06:49:d2).

Can anyone tell that this issue is normal or not.

i have done a normal setting and my entire network is running perfectly but i want to know whether it is normal or is there any setting to resolve it.

This statement also comes in LHG5, SXTlite5, Basebox5

Kindly tell me what to do.

Thank you.
