SWR on 10 M

[W9RE]

I just noticed that my SWR on 10 M was a lot higher then normal on an
antenna, 2.6 to 1 when normal is maybe 1.7 to 1.  I used a dummy load to
check and SWR was 1 to 1 on 160,80,40,20,15 and 6.  But on 10 is was 1.7-1.8
to 1 into the 50 ohm dummy load.  I was going to check it on 12M but
couldn't remember the exact frequencies but I then noticed the ATU was in on
12M.  I turned it off and on then went back to 10M and SWR was normal.  I'm
99.8% sure the ATU was not on while in the 10M position.  I don't really use
it.  Anyone else ever run into this?  Must have been operator error but I
don't know how.
