[Trlog] glitch

[Tod - ID]

I think this has been discussed previously --
 
Can anyone give me a clue as to when so I can check the archives.
 
I noticed a few times this weekend in the 160 contest that when I used the
band sheet to jump to a frequency where someone was calling CQ I got CW-USB
for the CW setting . Normally I  use CW-LSB and would have expected that my
CW setting would not be changed. Is there a setting that governs this? Any
ideas of what I should look for? 
 
Thanks in advance for any help.
