Products Not Showing up on Shop page

I just set up my website and have been adding products...only 15 so far, but have another 80 or so to go. Only 8 of my products are showing up on the shop page...the other 7 I've added aren't there. 

Do I need page numbers on the bottom and the customer would select the Next page or should I add all products on the same page and customers just scroll down to see all of them...which for now, I'm thinking I'd like. In either case, I'd need help with them showing up.

Did you set the visibility of each product to Public by publishing it?

Did this help? Please give feedback by clicking an icon below  ⬇️

Yes, the visibility is set to Public on the other 7 not showing up.  On the Save button, I don't have a drop down for Save/Publish/Schedule.  I can only Save, that's it - there's no drop down option there.  

The only thing I can think of that I did different, was that I chose Duplicate when I was adding products to save time on entering details and other information. Would that have caused this?
