Delete or Backspace don't remove my last click on Lasso Tool

Hello guys, I just get a new job and I'm setting all the configurations up to get all the Adobe Suite with my personal workspace, the main problem that I have it's when using any of the Lasso Tools I can't remove my last click using Delete or Backspace as usual. I've tried to Reset all the Tools, Reset the whole app configuration, Reset the app, Reset the PC, Push all the keys of my keyboard, etc. I also checked if the Backspace and Delete buttons of my keyboard are working properly and yes, they are. I didn't see any help about it in any forum or content on the whole internet. So, please give me a hand, it will be great. You can imagine how horrible is selecting without this feature in complex pictures and starting from scratch each time you miss a proper click. Thank you very much.
