Project specific settings in Preferences and Default Settings not taking

I would like to have specific and individual settings for each project. As of now, whenever I make any changes to Pycharm > Preferences > Terminal, this overwrites the settings for the subsequent projects. I want each project to have its own individual settings

Pycham > Preferences > Terminal

Start Directory

Shell Path

Application Name

File > Default Settings > Terminal

Start Directory

Shell Path
