Can you still check if you had another version of this font installed?
That is "the usual suspect" for glitches such as these. On the other hand, if you have a version installed, surely TypeKit would (a) overwrite it OR (b) not install the newer version alongside the older one ...
Haven't previously had Raleway regular, but as visable from the font menu above - for a while, I tried and used a "free version" of Raleway medium italic. Odd that it's still there. I removed it. The system font folder doesn't contain any Raleway fonts at all and I searched the entirety of the local drive for "raleway" but found no instances left.
The matter resolved itself. Weirdly enough. Had it for a few months - whined about it here - then it magically resolved itself. Yay!
