Basically, I have a set of changes on several (17) files. In the commit window (and maybe outside it too) in the changes view:

1. if I select only one file, I can see it's changes;
2. if I select all the files, I see changes for only part of the files, some files are just skiped and sourcetree says they have no modification;
3. if I select one of the files that is said to be unchanged, I see changes;
4. if I select all the files and check if the changes view are not mixed with changes of another file, I can't find the changes from the file skiped;

The screenshots I'm adding should be clearer.
