Unable to open prompt list by clicking on folder project icon

Hi guys

Dunno if its a bug or weird behavior, but look: when I’m on chatgpt web version, I can display in the left sidebar prompt titles I got in a specific project, by clicking on the folder icon:

But in MacOS app version, I’m unable to deploy the prompt list, it only open the project root content with the prompt window at right

Any idea if/how can I fix it? do you confirm you got the same behavior? thanks in advance.
