What I did was added new callsigns to the DB Explorer under Routes. I then populate them. So I was only playing with the Routes table.
After doing a few new routes for the DB I noticed, as I reported last night in another post, that I get weird info on the screen. The second line should be Reg-A/C type, I started seeing the type repeated twice . When I opened MyLog and the DB I found that, as you can see from the shots, that there are entries of the type or part of the type in the AR column which is causing it to show that info on my screen.
In some cases the whole callsign has been removed from the AT column to the AR column.
