TTL is ignored on delete if it present. It is set to 0 when sending.
2.5.4 - Delete An RR From An RRset
RRs to be deleted are added to the Update Section. The NAME, TYPE,
RDLENGTH and RDATA must match the RR being deleted. TTL must be
specified as zero (0) and will otherwise be ignored by the primary
master. CLASS must be specified as NONE to distinguish this from an
RR addition. If no such RRs exist, then this Update RR will be
silently ignored by the primary master.
