You will need to share a full example in order for me to explain why it works that way

I know what "NaN" means. I was hoping that by transforming the dataset into a dataframe and then returning back, the dataset variables would recover its original shape.

In xarray and pandas, "NaN" just means "missing value". This typically happens if your DataFrame does not contain a row for every combination of Dataset coordinates, for whatever reason.
