I changed the greeting in the terminal emulator, a bug with the translation of the core, how to fix it?

Question

linux

Ubuntu 18.04, changed the greeting in the .bashrc file:

if [ "$color_prompt" = yes ]; then
    PS1='\033[01;32m\$ \033[00m'
else
    PS1='\$ '
fi

When you press the up arrow twice, the previous command is not completely erased:
$ ssh [email protected] push
How to fix?
