Most probably the encountered problem is related to the way you configured the CSS styles in the custom skins for the RadRotator. I have attached a sample that can be used as a reference for incorporating the skins in your actual project. You should use the same model in order to achieve the desired result.
If the problem persists, please open a support ticket and try modifying the included example in order to reproduce the problem so that I can examine it locally and provide an according solution. If this is not possible, you can also send a simple, runnable project that isolates the issue.
