[rfDynHUD] Gap displayed with minuses instead pluses

[Evanderro]

I'm using rFactor with rfDynHUD ver. 1.3.0 and I noticed something weird.

When I'm in editor, gaps are displayed as it should, with pluses (+6.399, +8.365 etc.):

But when I'm in game I can see minuses (-0.549, -2.157 etc.):

Anybody know how to fix it? I'd like to have "+" ingame too.
