Please help me solve the problem of EA being bound to a Steam account

I just unbound my Steam account today because I no longer use my EA account and I need to bind a new EA account. However, when I tried to bind my new account to the Steam platform, it showed that my previous account had not been unbound. The most important reason is that my previous EA account had already been unbound. I would like to ask about the reason for this issue. Please help me
