Unable to overwrite previous program on nRF52832 using SES and nRF5_SDK_15.3.0_59ac345

I am able to program the nRF52832 but not all functionality is implemented.

I had previously programmed the device with a Nordic UART service and then tried to program the blinky example, but I still see the UART service when I connect via the nRF Connect application on IOS. The UART Service is the only service listed when I connect to the device. The device name updates correctly however.
