Some warnings are not marked

[OscarAkaElvis]

Hi, I'm using 0.1.4 on Pycharm 2019.2 and shellcheck 0.7.0

As is shown in this image, only the second one is marked as warning. The first one is not marked at first sight... no yellow line.

But If I set the mouse over the first one, it is shown as SC2886, look:

It could be nice to have all of them marked in yellow as warning. Otherwise is pretty hard to detect some of them. Thanks!
