You'll want to be sure all other autofill services are turned off in your browser first, as this can be caused by another autofill service interfering with LastPass' autofill: https://support.logmeininc.com/lastpass/help/how-do-i-enable-or-disable-my-web-browsers-password-man...
Thanks for that suggestion. I made sure all 3 Autofill options are turned OFF in Chrome, but the problem persists.
Anyone else have this problem? Or a solution?
If this is only happening on one site and you've made sure your browser autofill options and browser password manager are disabled, it may be the way the site itself is programmed/coded and be outside of LastPass' control, could you try adding the site as a Never URL or try disabling the LastPass extension when on that site and testing again?
