Issue with two-factor authentication on Zondacrypto

I am trying to set up two-factor authentication for my Zondacrypto account using Google Authenticator. I have paired my smartphone with the account, but when trying to generate a code, instead of one, several codes are generated at the same time. After entering the code, an error message about an incorrect code appears. I have tried this several times and each time more codes are generated, none of which are correct. I should also mention that the time is synchronized on both the smartphone and the Google Authenticator app.If anyone knows the reason, I would appreciate their help.
