The problem could be many things. You haven't given us much to go on, so I'll mention one possibility.
You may have taken a vendor supplied DMG and just uploaded it "as is" for your software install.
The problem with this is Jamf Pro uses the DMG format, but expects to see a folder structure on where the application should go. Since vendor DMGs don't have any folders, it just installs it at the root level.
A less likely possibility is that you created a Composer package or DMG that simply grabbed the app from the root of the hard drive and it copied that path in. I'm guessing you would have noticed this, so I don't think that's the issue, but am mentioning it in case it was not a vendor DMG you used.
