Change of connection parameter response out of sequence

Hi Dialog team.

Can anyone tell me why I am getting an out of sequence response to my request for connection parameter change ? (SDK 6.0.8, iOS 11.4)

Slave -> Master - Rcvd Connection Parameter Update Request (so this is the remote unit requesting higher speed connection parameters prior to doing an OTA)

I expect

Master -> Slave - Control Opcode - LL_CONNECTION_UPDATE_REQ, but instead I get Master - > Slave - Rcvd Connection Parameter Update Response (Accepted) the very next packet.

Then some time later I get the Master -> Slave Control Opcode - LL_CONNECTION_UPDATE_REQ

The last two responses from the Master are out of sequence according to the specs.

I do the exact same request after service discovery but to slow the connection down. In that instance, the correct sequence is observed.

Any ideas what's going on ?
