[Elecraft] K3 Sub Receiver forces FSK D to AFSK A

[Bud Governale, W3LL]

I've always used FSK D mode.

Since updating to 3.57 when I turn on the Sub Receiver the radio goes into AFSK A. 

How do I stop the SUB from changing FSK D to AFSK A?

In the past the radio was always in FSK D and the SUB did not change this.

I'm in VFO A and check DATA MD. It says FSK D.

Turn on SUB and check DATA MD it now says AFSK A.

Thanks,
