I don't Know who needs the solution now. But, I was in search of one and couldn't find it. BUT, I have figured out something, it worked for me, may it work for you too.

SO, when it shows, ( See the image ) 1st bullet point :- (ID: No ID) cannot be saved. 

Just ignore it,

now listen to me. Understand that through this, it is notifying that which listing has the issue (here for example, Glowing Buzz Pure Vitamin E Oil 10ml (100%...) has the problem.

And what problem is it? that's written in the 2nd bullet point. So for eg, here the issue was that characters were above the character limit.
And as and when I solved and saved it, everything worked!

I was stuck on this problem for days and couldn't find any solution too. 
Now, It worked flawlessly for me, you just need to focus on the bullet point after the [ (ID: No ID) cannot be saved ] bullet point where [ (ID: No ID) cannot be saved ]  is telling the name of the listing that has the issue.

I even gave IDs and everything else! It worked perfectly, Let me know if it works for you too!! Thanks :)
