Problem with creating product bundle

I realize this thread is from 2016, but I am trying to create a bundle and when I click on the Add Products to Bundle button, it jumps back up to the top of the page with the red error bar saying I need to add at least 1 SKU to the bundle to activate. I have saved all the general info I need, just trying to get products on this bundle, but can’t seem to accomplish that. According to the documentation and video, I have done everything right leading up to adding products. Please help! Trying to launch this for our tasting rooms this weekend. Thanks!
