mark as resolved?

So I upgraded from 2.0.8 to 2.0.9 and I have about 10 files that I need to select mark as resolved.

Im sure this is simple but when I review the changes, is the green what was added and the red what was removed?

My site does not load correctly and I assume its missing the data that is marked as red.

Any ideas? Ive reverted back to 2.0.8 for now but would like to know what I need to do in 2.0.9 to fix whatever it is that 2.0.9 is breaking.
