Hi Dustin,
Thanks for letting me know your settings, I just site up my test portal to match your settings and I was able to replicate the issue of the Quantity field is enabled to be hidden, the Quantity is still being displayed on the Confirm and Confirm Status pages as well as the Confirmation Emails.
I have logged this to our Bug Tracker system as Bug ID 288 to be resolved as soon as possible and we will reply to this thread as soon as an update is available.
If you would like a quote to prioritize this fix into programming immediately, please send an email with a link to this post to
sales@smith-consulting.com. It is not required that you sponsor this fix, just if you would like immediate attention to the issue you reported.
Thanks!
