API status message with incorrect frequency

When starting SmartSDR, If I monitor the status messages sent by the radio to SmartSDR the initial status message has the wrong frequency. I'll describe the conditions, it's easily repeatable.
Open SmartSDR, select 40 meters, create a slice at 7,250,000 (lLSB) and a slice at 7,300,000 (LSB). Close SmartSDR. Open SmartSDR again while monitoring the status messages, you will see the following (I've filtered the list to only show messages containing "RF_frequency":
As you can see the first status message containing "RF_frequency" says that Slice 0 has a frequency of 7,270,704 (incorrect!) and is immediately followed by another status message with the frequency at 7,300,000 (correct).
Similarly, the first Slice 1 message has the frequency at 7,305,000 (incorrect!) followed by another status message with the frequency at 7,250,000 (correct).
Although the result is that the correct frequencies are displayed it seems strange that this sequence of events should occur. I believe that it requires multiple (2?) slices to see this occur. I haven't tested many other scenarios.

Good find Doug. We'll look into it. Thanks for reporting this. For tracking, this is #6424.0

Thanks Eric.
I only found it when I introduced an error into my client code that ignored everything but the initial frequency received. Once corrected my client works fine and ignores the wrong values (as does SmartSDR).0
