Why are most columns' Properties categorized as Dropdown Single Select when importing from Excel?

I have a test Excel file with 40 rows and 31 columns that I'm importing. A majority of the columns (approx. 28) are being imported in with Dropdown Single Select properties. I'm creating a workflow that will eventually automate copying rows to other existing sheets. The way the spreadsheet is being imported is creating more manual clean up work than I anticipated. How do I get the column properties to be Text/Number?
