The second one is not registering with you. You will need to look at the log to see if they are attempting and failing, or trace the register request and see where it is getting lost.

Note, although not relevant to the issue, the combination of insecure=invite and host=dynamic is very strange. It reduces security and I can't think of any valid reason for using it. It would also be unusual to need insecure=port in this context.

Also note that questions requesting peer support help should go on Asterisk Support. Asterisk General is for general discussions and comments. Also please cut and paste logs and console output as text. It is easier to search them and check for certain sorts of error.
