When applying predict.dummyVars to a different data set factor levels do not persist in the creation of the design matrix.
I noticed this issue with caret version 6.0-52. Due to IT constraints I am not able to install the latest version of caret, but checking the code for dummyVars.default and predict.dummyVars it appears this is still an issue.
