Hello @goldenmoon,
Hope you are well.
Please make sure that you are using the latest version of WPDM.
If still, the problem exists, 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
