Upload button rejecting legitimate files

Hi,

On https://www.isaiah-house.org/career-application/ there is a Jotform that is supposed to allow uploads of several formats of documents. When I test a .docx or a .pdf it rejects them saying they have an invalid extension. Would you please check that out?

The file types extensions the options should not have dot(.) before them.

Just add the extension names and separate with comma sign(,)

Ex: pdf,doc,txt,png,jpg
