Imported Data Plotting incorrectly

Any ideas why the data is plotting differently despite using the same X-Y axis data reference?

Below is a link with a screenshot of the Scatter Plot using Plot.ly vs. a different program (PAST).

I used the import feature, would the formatting of my excel file have anything to do with it or are there other settings I need to adjust?

Thank you for any help.
