Unexpected SC font color changes

Dale Drake

I recently started seeing this behavior when working a station from SC in WW.

I see a cw spot for a station from a country that I already have verified ( font color set to black) but I want to work it anyway so I double mouse click on it 
SC passes the info to WW and Commander QSY's the rig.
I listen for the station, copy his call sign and call him
He answers my call so I click Begin in WW
We complete the QSO and I click Log in WW and DXkeeper is updated.
This is where the unexpected happens. After logging the QSO all the existing spot in SC for CW, on that band, and that DXCC, fonts change color to unworked B or M (font is set to green).  The Needed column in SC stays blank.

It doesn't happen all of the time and when new cw spots come into SC afterwards they're font colors are all normal.

I've been using DXlabs for over a year now and never have seen this until recently. I can't correlate it to any changes in software or the operating system on the PC.  I haven't tried to duplicate it in any other mode.

I looked but couldn't find anything in the help files or the wiki that refers.

It's not a big deal but seems weird to me.
