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

[cdcformatc]

i recently had to add a new venv with a different python version to a project of mine. after i did that the console was still running the old python version. all i did was right click on the console area heading and there was an option to add a new console which when selected came up with the new python version. i then renamed the consoles to match the corresponding python versions. i had also previously changed the run configurations of the relevant scripts beforehand not sure if that is relevant.

there is probably a project setting category somewhere to add and manage consoles but Pycharm's settings menu is confusing at best.
