Physical sample numbers are not in sequential order

Hi Everyone,

I am creating an inspection lot through QA01 and using flex specs. If I create 30 samples, let's say, and save, it will create 30 physical samples. The problem I am seeing is that sometimes the sample numbers jump around numbers, so I will get 110000936 for the first sample and then 110000950 for the second sample. Does anyone know why the numbers are not in sequential order and/or how to fix this issue?

Thanks,
