MATLAB: Structure is pointlessly nested within itself when I save it. How to unnest

MATLABsavestructures

Maybe kind of a stupid question, but I had a structure saved to disk–let's call it data1.mat. My script would have a few lines like this:
data1 = load('data1.mat');
…
There would be a few of these. Then my script commands would access variables like this: 
some_command(data1.some_variable)
I edited some numbers and wanted to update the saved file data1.mat. However, now when I load the updated file, it now has an extra "layer" of "data1". So to access a variable I now need to do:
some_command(data1.data1.some_variable)
This is stupid. How can I undo this?? This should be simple but for some reason I can't figure out how to remove the pointless extra level. I tried selecting all the fields inside the structure layer and saving them to disk, but the same thing happened.

When you save the struct that you received from load after modifying it, use the '-struct' option in your save call.
>> x = 1:10;
>> y = magic(5);
>> S = struct('x', x, 'y', y);
>> save('mymatfile.mat', '-struct', 'S');
>> whos -file mymatfile.mat
  Name      Size            Bytes  Class     Attributes
  x         1x10               80  double              
  y         5x5               200  double
