Heatmap MetaboAnalyst 6.0 - reverse order of the compounds

Dear Sirs.
I am working with MetaboAnalyst 6.0, and I am trying to process my data to perform a heatmap. I choose the option “Do not cluster - Features”, and then I noticed that the programm perform the reverse order of my compounds, and not in the order I submitted the file. I want to understand what could happen, if this is a mistake in the code, or if I am missing something.

Best regards
