Issue with ATU status message

The following is an excerpt from a log of messages received from the Radio hardware to my custom client program after performing a "normal" startup (initializeRadio). I'm only showing the ATU messages. Note that in the third and fourth messages that the "atu" string appears in the middle just after "TUNE_MANUAL_BYPASS" and just before the "memories_enabled".

Could this be a bug? Admittedly, my code is new and may not be correct but after looking at it for some time, I think I'm actually receiving what is shown below. I've actually logged it coming in from the socket before any processing is done in my code.

It looks as though the "_enabled=0" portion of the message immediately following the "atu" has been dropped.

It's very repeatable, I've done it multiple times with the same result.

c4|sub atu all

S7F0D191E|atu status=TUNE_MANUAL_BYPASS atu_enabled=0 memories_enabled=1 using_mem=0

S0|atu atu_enabled=1

S7F0D191E|atu status=TUNE_MANUAL_BYPASS atu memories_enabled=1 using_mem=0

S7F0D191E|atu status=TUNE_MANUAL_BYPASS atu memories_enabled=1 using_mem=0

Here's the sequence of commands that I sent to the Radio (they're in Swift but I think you get the gist):

commandToRadio("client program xxxx")
commandToRadio("client gui")
commandToRadio("sub tx all")
commandToRadio("sub atu all")
commandToRadio("sub meter all")
commandToRadio("sub pan all")
commandToRadio("sub slice all")
commandToRadio("sub gps all")
commandToRadio("sub audio_stream all")
commandToRadio("sub cwx all")
commandToRadio("sub xvtr all")
commandToRadio("sub memories all")
commandToRadio("sub daxiq all")
commandToRadio("sub dax all")
commandToRadio("info", callback: infoResponseCallback)
commandToRadio("version", callback: versionResponseCallback)
commandToRadio("ant list", callback: antListResponseCallback)
commandToRadio("mic list", callback: micListResponseCallback)
commandToRadio( "client udpport (vitaManager.vitaPort)")
