[WriteLog] Another issue

[Don Hill AA5AU]

Today I've been plagued by another issue while running WriteLog in CQWW RTTY.

On occasion, a station will show up on the bandmap in Yellow which means it's a multiplier. But on occasion the station in Yellow is
not a multiplier. When I click on the call (I'm single band 15 meters), the radio goes into split and the transmit VFO gets put on
10 meters.

The station spotted is definitely on 15 meters and they are not a multipliers for me. 

Any ideas?
