Episodes missing on the peacock network seaquest DSV/2032

To be honest iliked the peacock network a lot until i started to watch a show i liked a lot when it orginally aired.  That show is Seaquest DSV/2032.  I was watching it on peacock and noticed that only 36 of the 57 episodes are listed on peacock.  Why  are there episodes missing?  is it a problem with my box or is it a programming problem?
