Tasmota 14.3.0 standard version running on ESP32. I'm experimenting with Matter. While it deos work well with Matter I noticed that Tasmota is advertising that it is in commissionable mode when it is not.
I'm using WireShark to capture the network traffic. Attached is the report by wireshark.

My Tasmota device is at address 192.168.1.115 and the capture below comes from it. Furthermore advertasing this on mDNS means that the device is in commissioning mode but it is not. Commissioning mode must be start manually and lasts 10 minutes.

Frame 13903859: 341 bytes on wire (2728 bits), 341 bytes captured (2728 bits) on interface \Device\NPF_{B1732F1B-3028-4851-B79B-EF51C35ACB99}, id 0

Converted to discussions, since issue template not filled and not latest Tasmota version used.
Only latest Tasmota version is supported. Please try again with actual one.

Sorry. Moving to another one that has SAME problem and has LATEST Tasmota version 15.1.0. IP address is 192.168.1.125.

Here is the Template

{"NAME":"ESP32-DevKit","GPIO":[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,1,1,1,0,1,1,1,0,0,0,0,1,1,1,1,1,0,0,1],"FLAG":0,"BASE":1}

Here is the WireShark capture that confirms the problem
