Help with LOGICAL_OP block and shift register implementation in XCOS integer

I’m using XCOS integer palette in Scilab 2025. I could build a logical function, but logical_op block does not update to newly set logical function, as is seen in my screenshot. Did I make something wrong?

I would also like to build and simulate a shift register using DFLIFLOP. To start simple I built a 2-bit shift register. But it does not work properly as seen in my screenshoot below. The second Dflipflop output D2_out is not delayed in comparison to D1_out as it should be.

What did I did wrong?
