[Dx4win] Export/Import

[Vlad UA6JD]

Hello dx4win,
I export part of the log using
File|Export/Import select "DX4WIN Version4.06 and later" then
File|Export save as aaa.dxn/aaa.dxq
Then open new file bbb.dxl and try import this "aaa" log
File|Export/Import   select "DX4WIN Version4.06 and later" then
File|Import select aaa.dxn/aaa.dxq
When I check it was errors in Notes "Error:Satellite=X"
But all QSO which I am enter direct in main window read without errors.
Error was ONLY QSOs which I was import before from ADIF.
It was Contest QSOs. Using CT[K1EA] and then convert it to ADIF by
c2a.exe. Then Import to DX4WIN5.03 as ADIF file.
So my question:what I do wrong? and why contest QSOs,imported before
from ADIF, indicate error? can I import part of log in DX4WIN5.03
format(aaa.dxl)?
