The terminal count output of a counter is on only for one clock period. So, with an input clock of 375Hz, the LED will remain on only for 2mS. The rest of the times it will be off. When you invert this signal, then the 2nd LED will be Off for 2mS and will be on the rest of the time.
Instead of the Terminal count output, use the Compare Out output of the Counter and connect it to Row_0_Output_0. Also, set the CompareValue of the Counter to 128. This will result in the LED blinking at a rate of 1.4Hz with 50% duty cycle and the other LED will be out of phase.
