update failed: 'RRset exists (value dependent)' prerequisite not satisfied (NXRRSET)

hello,

i have 9.2.1-9 running on an up2date red hat 8 box.

whil trying to implement ddns (dhcp updates dns) i noticed that the
client is able to register its address in the reverse zone, however, the
forward zone is not updated and the named.log gives the error in the
subject line of this message.

can anyone comments on why this is happening?

many thanks
