Unwanted operating mode change on 40 meters

I think that this is more of an issue with my Log4OM logging software than it is with my Elecraft KX3 but I'm posting this to both the KX group.io and the Log4OM forum just in case.

My KX3 very happily communicates with my Log4OM software, correctly recording operating frequency and mode into my computer log. It will also change my rig's frequency if I click on a spot listing shown in the logger.

But here is the strange thing... With my radio set for CW, as I tune across the lower end of 40 meters, the mode in the logging software changes to FT4 when the frequency is between 7.047 and 7.048 MHz. The radio does not change, it is still set to CW, but the mode shown in the Log4OM window, that is used to enter new QSOs, switches into FT4 for that one KHz of the band. It switches back to CW when tuned past this segment. It also has nothing to do with what is being received by the KX3 at the time, for example ARRL code practice at 7.0475. I have not been able to find any settings in the software that would cause this. (I should mention that I have never done any digital operating with either this radio or software.)

Any ideas on what might be happening here?

Thanks and 73,

P.S. The Log4OM version is 2.30.1.0 and in the KX3 I have MCU 3.02 and DSP 1.52. The computer is Windows 11.

With some research, I've figured it out. I needed to go into the band plan configuration files and remove the special 40-meter FT4 frequency. The mode now stays at CW for 7.047.
