If your login name (user name) is always displayed incorrectly when you log in to Shopee, it may be caused by the following reasons:

1. Input error: Make sure you have entered your login name correctly. Usernames are unique and case-sensitive. Please check for spelling errors, extra spaces, or other errors.

2. Account problem: If you are sure that the login name you entered is correct, but you still cannot log in, there may be a problem with your account. Please try to reset your password or contact Shopee customer service for help.

3. Network problem: If your network connection is unstable or slow, the login process may be affected. Please check your network connection to ensure that the network is stable and the speed is sufficient.

4. Browser or device problem: Sometimes, problems on the browser or device can cause login problems. Try clearing your browser cache and cookies, or log in using another device or browser to rule out these factors.

5. Website maintenance or upgrade: Shopee may be undergoing maintenance or upgrades, which may affect the login function. Please try again later or check Shopee's official channels for any maintenance or upgrade information.

6. Account Restriction: If your account is restricted or suspended for violating Shopee's regulations, you may not be able to log in. Please check your email for notifications about account restrictions. If necessary, please contact Shopee customer service to resolve the issue.

If the problem persists, please contact Shopee customer service for assistance. They can help you diagnose the problem and provide a solution.
