There is no guaranteed order with UDP packets. (TCP is different, it has guaranteed order and delivery.) And the UDP header doesn't contain any information about the order, it contains source and destination ports, length and checksum.

What is the actual problem?

How have you collected the logs?

packets id aren't in order and i collect the low tcpdump port 3074 and src 197.37 -nvvl

Ok but what is the real problem? What application doesn’t work because of this?

you mean the "id" field values are not in order? that's normal because they are part of IP called identification header and they are supposed to be unique values, not necessarily strictly in sequence. see https://datatracker.ietf.org/doc/html/rfc6864
