The SPIM_1 component switches SS to '0' before and to '1' after SPI communication.
You manually use the command SS_1_Write()
You need to make up your mind : Automatic Control SS via MSPI_1 component OR manually SS_1_Write(). NOT BOTH !

Look like hardware crosstalk noise, please use an oscilloscope to capture the signal waveforms, do not use logic analyzer
