Do these scores make sense?

Hi everyone, i am a little confused about the scores I am getting (see image attached).

I followed the solution in Aarshay Jain’s blog post closely, although I did more feature engineering than he did (for example I created a variable Item_Sale_Category with high, medium, low).

The scores I am getting for the various models don’t make sense to me. Surely, at least the Ridge Regression Model should perform better than the baseline average model, or am I misunderstanding how the score is calculated?

Thanks for any input!
