DbSet mock, no results while calling ToList secondly

Question

I\'m trying to mock DbContext and DbSet. This works for my previous unit tests, but problem occurs while my code was calling ToList method on DbSet second time.

If you put a "Where" clause before the .ToList() call, the data should remain present.

var a1 = dbset.Where(m => m != null).ToList();

var a2 = dbset.Where(m => m != null).ToList();
