There could be several issues with this, please give some more info. How 
are you signing your zone? dnssec-signzone? automatically using bind? 
Some other software?

If you're using dnssec-signzone and pass it old signed zone data it 
regenerates signatures only if signature end time falls within a period 
defaulting to 1/4 signature valitity time (so with default signature 
period it's 7.5 days). If you re-sign your zone say 10 days in advance, 
it won't change old signatures. You can change it with -i. Other 
software probably behaves similarly.

Also, if you're signing your zone off-line and upload it to bind, did 
you remember to change SOA and reload master?
