Endpoint IP often cannot be changed through webgui

Endpoint IP often cannot be changed through webgui，After restarting the system and trying many times, the webgui shows that the endpoint has been changed, but the actual cmd wg command shows that the endpoint IP is still a very old address.

/usr/local/etc/wireguard/ tun_wg3.conf Why is there no endpoint in the configuration file here? Where can it be found?

i setup endpoint is ipv4 address, but it still use ipv6 endpoint address.
