Why does Sourcetree show line difference when there isn't one?

[jwright]

Looking at a changed file from my git repo in Sourcetree, it has some legitimate changes in it.  But when I compare versions of the file and look in the Sourcetree 'differences' pane, it is showing a line that (I believe) was unchanged.  It show a red -, and green + for the same line #23, with the same text, same number of spaces, etc:

 

I guess my question is: why is this marked as a "difference"?  Thanks for the help!

Hi @jwright,

Welcome to the Atlassian Community.

It could be that there is a white space change on that line. You can set it to ignore white space by clicking on the cogwheel above the diff window.

Thanks @Mikael Sandberg for the prompt reply!  I thought it might be whitespace, but the two lines seem to have exactly the same number of characters and whitespace.  But, indeed, if I check the ignore whitespace option, the questionable lines disappear.  Thanks for the tip.  Still bothers me a little bit, but thanks!
