Run ps -p $$ at the command line to determine that you are, in fact, using a bash shell.
Realize that you are in zsh, which means you should be editing your profile in .zshrc.
Copy the offending lines from .bash_profile to .zsh, OR
Modify your .zshrc to directly source your .bash_profile. (By adding . ~/.bash_profile, although I'm sure there's a reason not to do this.)
