Super ContributorHi,
Unfortunately, the VWF simulation tool is a legacy feature used in Quartus Lite/Standard editions, and there are no plans to fix issues related to it.
If it works for your design, then you're in good shape.
If not, I recommend simulating using the Questa Altera FPGA Starter Edition simulator tool. I tested your design in Questa, and the waveform was correctly reflected.
Additionally, you can use the NativeLink Simulation to automatically compile your design, Intel IP, simulation model libraries and testbench.
