Last things first, if all of the files were properly transferred, the success statement should go away when another "option" from the admin panel is selected; however, that seems to not be the case. Recommend reuploading all files.
As to the first issue, that would be most likely a CSS issue as it relates to the device you are using (ie, an iDevice, mobile phone, desktop, etc...) Normal installation and usage does not have that problem, but it could also be related to the above.
