Looks like when i disable the expression the logo color comes back. Not sure what that expression means but looks like that could be the problem.
The expression links the opacity of this precomp to the "Controls" layer in "Scene" composition. there is a checkbox on or off to set opacity to 0 or 100. guess that's what the creator of this template had in mind. Still it does not explain how it is white. Probably a duplicate of the logo precomp. probably the one underneath called "Text 17 end text" coloring it white since it does have an effect applied to the precomp layer.
Anyways, if disabling the expression solves your problem then it's good news.
