Power Apps - Dropdown adding multiple decimals to numbers

Hi, I'm confused as to why a dropdown control is adding multiple decimal places to the underlying number when displayed.

The source for the dropdown is a choices field (named 'company_number') in a SharePoint list (named 'batch_header'). The choices come from a list with the field formatted as a number but with no decimal places. You can see the additional decimals being added in the image below.

I need the source whole numbers to be displayed, with no decimal places. It seems to be a problem with the dropdown control itself, but I'm not sure.
