My BDS (version 1.16.40.02) has inconsistent internal and external ports, which makes it impossible for me to join my server and play with my friends, and although I try to change many ports, they are always inconsistent

(I can't upload pictures, so I try to describe what happened)

When.
IP v4:30405
IP v6:31405

And then.
IP v4:19132
IP v4:19133

---------------------------

When.
IP v4:19132
IP v6:19133

And then.
IP v4:random (1-65535)
IP v4:random (1-65535)
