I saw those strange records and asked them about that.  They answered that  they
added the records the same way they added them for everyone else and that they
were correct.  I suspect that they did not read my email very closely.  I had
not realized that a missing '.' could do that until you pointed it out.  Now that
I think about it, I expect that that is what is wrong.  I will have to pound on
them Monday morning.
