Hello @flakeyguide,
Hope you are well. And sorry for the inconvenience.
First of all please make sure that you are using the latest version of the WPDM plugin.
I hope it will work fine then. If it doesn’t work, then please provide us with your temporary wp-admin login details and site URL in a private reply for checking the issue.
Also, please share the related page/file/package URL with us where the issue exists.
However, it will be very cooperative if you record me reproducing your issue using a tool like this?
It helps me to quickly figure out the issue and squash it immediately.
Thank you
