STM32F401 Nucleo SPI Clock problem, using STM32CubeF4

I am using SPI1 with HAL low level drivers, STM32CubeF4.

I have used the following SPI configuration:-

SPI_HandleTypeDef hspi;

hspi.Instance=SPI1;

hspi.Init.Mode=SPI_MODE_MASTER;

hspi.Init.Direction=SPI_DIRECTION_2LINES;

hspi.Init.DataSize=SPI_DATASIZE_8BIT;

hspi.Init.CLKPolarity=SPI_POLARITY_HIGH;

hspi.Init.CLKPhase=SPI_PHASE_1EDGE;

hspi.Init.NSS=SPI_NSS_SOFT;

hspi.Init.BaudRatePrescaler=SPI_BAUDRATEPRESCALER_256;

hspi.Init.FirstBit=SPI_FIRSTBIT_MSB;

hspi.Init.TIMode=SPI_TIMODE_ENABLED;

hspi.Init.CRCCalculation=SPI_CRCCALCULATION_DISABLED;

hspi.Init.CRCPolynomial=0;

HAL_SPI_Init(&hspi);

After sending some bytes on MOSI. On logic analyzer, I see clock and MOSI data are mismatched.

This is a very zoomed in pic, If required I can send the whole logic analyzer file.

Please help.
