How to suppress glitch caused by Expression Calculator in Simvision?

Hi,

I putted an expression like,

dut.arvalid===1 && dut.arready===1 && dut.araddr < 'hA0000000 && dut.araddr > 'h90000000

and found some glitch in the waveform,

Is that glitch really meaningful? How can I suppress those glitch?

Thank.s
