Hello, I am hoping for some assistance .I've just updated all of my products to include a default product revenue schedule. However, one product is refusing to allow me to add a revenue schedule. Also, any new product that I add to the system won't allow a revenue schedule. I have NO idea what the problem is. The Error turns up on the Revenue Schedule Type field, and comes up regardless of the options I put in. Also, bizarrely, I had no problems at all with the other products. I simply can't understand it. Has anybody else had this problem? .Any detailed pointers or <a href="https://blog.advids.co/20-animated-explainer-videos-that-are-awesome/">explainer videos</a> will be appreciated. Please help me out. Any help will be appreciated. Thank you.
