Mismatch in shapes when Checking to see if train label are the same (before and after window split)

[jonjont-j]

I am currently going through the course extra curriculum for time series and I am changing the window sizes. When I get to the cell to verify if the train_labels and y_train are the same before and after window split I get false. In the course with window size of 7, the verification cell produces an output of true. Is this an issue if so how can I fix? I have adjusted to range from 8 to 3 with no luck. When changing back to window size 7 and range 8, the verification cell produces a true output. Thank you
