Can't expand code
Hi all,
I've got a strange problem. I have a css file, open in DW and there is a section that I can not open/expand.
Line 71 (below) has the collapsed code, then jumps to 228.
I have tried clicking on the arrow, usually works; selecting the line then right-hand click>Selection>Expand Selection.
Neither method works.
I can open the file in notepad and all is well, I can view it online and again all is well.
I have rebooted my computer, still nothing.
All other 'sections' work fine, just the code collapsed in line 71
Any ideas?

I am using DW 2017.0.1 Release 9346 build.
