Found where the problem is but not the solution yet. I had the exact problem. Some of my gallery images could not be edited and others could. When you click on the edit icon, nothing happened.
It's caused by adding an apostrophe in the title or description!!!
As a temporary workaround you can use the key to the left of your number 1 key. It looks like an apostrophe and won't cause any problems.
Hopefully someone can reply to this post if they have found the fix...
