Dreamweaver replaces my code
Hello, guys!
I have a strange problem in Dreamweaver.
When I'm trying to add something before the existing line of code, it just replaces with code I was gonna to add!
You can see it on line 37.

OS X El Capitan 10.11, Dreamweaver CC 2017, 9346.
What could I do? Thanx a lot for your answers!
