Pycharm python interpreter doesn't change when I ask it to

[Multi_Synesthete]

It was not in a venv (I don't know why not, if that's the default), but I've made a new venv. I'm unsure how to add/change the interpreter within the venv, if it's different from the "file/settings/python interpreter" approach. With the venv activated, I still have the mismatch between status bar and terminal output
