Just to expend on that ...
There is also min-lease-time.

If the client specifies a desired lease time then the server will give that subject to min and max lease times.
If the client does not ask for a specific lease time, then the default lease time is offered.

As already mentioned, the first thing to do is look more closely at your packet captures. Check which devices the packets come from, and what's in them - particularly what options the client sends.
