[Dx4win] Import log after CTY upgrade

[IZ5FSA]

I've upgraded DX4WIN with latest country file version.

I've exported my log.
I've exported QSL Manager info.
I've overrided CTY file.
I've imported QSL Manager old info.
I've imported my exported log in a new one (DQ6 format to DXL).
I've got "no errors found".

But...

I've lost my Iota Award info (Submitted, Checked). All other Award info 
(Custom, DXCC) are safetly imported but IOTA Award Info are not. I'm 
using latest DX4WIN version and build (7.02.15).

Is it a bug?
