Reverse DNS records missing

[tookawhile]

I have one Forward Look Up zone an a Reverse Lookup Zone, some of the entries are not being replicated to the Reverse Look Up Zone, even if I re-apply the "Update associated pointer record". I've only just noticed this today, but I now for fact that it looked Okay a month or 2 ago. Is the only way to fix this to manually add a reverse look-up record?

I have 2 DCs.

Anybody?

Is this normal?

Not sure if this has something to do with the issue, I have host names in the forward lookups which have upper case characters, for example, J-DOE.mycompany.com, and on the face of it, it looks as though it is all of these that are not getting the reverse entries created.
