manjaro update changes my default bash to zsh ? ! how to change it back ?

After system update to 5.10.84-1-MANJARO, as usual it changes my themes and desktop photo and this time it changes shell to zsh.. i how to type bash everytime to get my old familiar bash back.

Every update is a waste of my time to change setting back.

Code:user1-pc% chsh -l
/bin/sh
/bin/bash
/bin/zsh
/usr/bin/zsh
/usr/bin/git-shell
user1-pc% chsh -s /bin/bash
Changing shell for manjaro-andrew.
