In addition to what DoctorOhh suggests, check in Settings / Formats and folders to see priority order of formats. Ensure that epub is at the top. Consider unchecking formats that you actively do not want sent to the device.
One change that could be a cause: by default new installations of CC now accepts all formats, including the Amazon ones (AZW, AZW3, etc). This change was made because too many people couldn't make CC work with the odder formats such as comic books. Before the change, if you sent an Amazon format book to CC, calibre would ask you if you wanted to auto-convert it to EPUB. Now, calibre just sends the format. DoctorOhh's suggestions are aimed at determining if something like this is happening to you.
Unless you have hidden the information you can see the actual format in book details by looking at the file path.
