[Dx4win] Why LOTW FLAG and DATE setting seperate?

[george]

I just up-loaded 5 new QSO's to LOTW.

First, I found that some of these QSO's had the LOTW flag marked Y. I hadn't 
even up loaded them yet?
In version 7 I just filtered for "N" to get the QSO's that hadn't been 
up-loaded yet. Easy, yes.

Second after marking these flags N, as I felt they should be, and then doing 
a search on the LOTW flag "N" I was ready to up-load these 5 QSO's to LOTW. 
I up-loaded these 5 QSO's to LOTW manually.

All went fine until I returned to DX4WIN and went to the LOTW in the QSO 
window and set the LOTW flags. It set the flags but not the LOTW up-load 
date?

I went back and set the LOTW flags back to "N" and went to LOTW in the QSO 
window and set the up-load date. This then did not set the LOTW up-load flag 
to "Y"?

What am I doing wrong? I use to do this as two operations in version 7 with 
"multiple operation" for the date and then setting the flag to "Y".
Thanks.
