Error in batch effect correction tool

I have encountered an input file format problem when using the batch effect correction tool. Hope you could kindly help me.
I have reformatted my input file according to the example of Dataset 3 provided in the platform, but got an error message: Your data is not eligible for this method! your data or format is not valid! Please double check!
I have no idea why the file format is incorrect. Attached is my input file for your reference. It would be great if you could give me some clues/suggestions about how to correct the file format.
