I am on a Mac using iTerm2 and zsh v5.7.1. When I login from my local computer to the remote computer using 'ssh', most of the characters are repeated at the prompt as I type. Clearing the line with Ctrl-L displays the correctly typed input. I am reasonably sure this is an issue of my prompt using UTF-8 and Esc characters. If I immediately run 'bash' after logging in, I have access to a prompt without special characters, and thus no repeating characters. My standard prompt is Powerlevel10K.

I obviously do not see these extra characters when I am using that 'remote' computer locally, but only when I 'ssh' into it.
I am hoping someone can point me to the offending file or command, such that 'ssh' properly recognizes the remote login environment and prompt.
