Unable to Change Phone Number Country Code on ArcBlock Profile

There is a bug on the profile editing page of the ArcBlock platform, where users are unable to change the phone number country code to Indonesia (+62) even though the option is available in the list. After selection, the country code does not update and reverts to the previous default. This issue persists despite attempting several solutions such as logging out and back in, clearing cache, and accessing the platform through different devices or browsers. This bug needs to be fixed promptly to ensure a better user experience.
