<div>As you can see, the time information in the first column was confused after 100000 (corresponding to 100ns). So we tried to correct the time information, and the problem seems solved. In our case, we made minor modifications on the

</div>
<div>I don't know if this is the best solution but I am reporting this and hope it is helpful to others. And the issue can only occur when we use an exchange frequency smaller than 1ps and run the simulation longer than 100ns. Could you identify if this is
 a minor bug or just limited to our case? Thanks a lot!</div>
