download available time isn’t working

Thanks for the message but not sure if understood.
Download Availability Period: I have a calendar icon to click to say when to make available and when to expire. This is found under packages and in a particular package. I am assuming this is looking at the wordpress time setting in WP core. That being said when I specify the “download” button doesn’t turn on and off according to my settings.

I am going to purchase the add on and see if that works.
