Exported pictures lose persons' identification

I wouldn't class this as a bug. I'm not even convinced that in all cases of the export it should retain the face data.

Consider these two situations:

(a) The image from which the export is made has had the face/s recognised, and the face metadata embedded in the image.

In this instance, if you examine the exported image in ExifTool you will see that it has the face metadata embedded (though it doesn't show in ACDSee View Mode)
You can also retrieve this face data from the image by simply selecting the image and doing a Tools>Face Detection>Import ACDSee Face Data, and the face details read from the metadata in the image will be added into the database and will then show in View mode.

(b) The image from which the export is made has had the face/s recognised, but the face metadata has not been embedded in the image..
In this instance, if you examine the exported image in ExifTool you will see that the face metadata is NOT present.

Now in both of the above cases the exported image is a new image. Its Creation and Modified date stamps will be different, and as the export could have been made from either Develop or Edit, as well as from Manage mode, the "new" exported image may have had changes made (for instance Crops or rotation) that would make the original face positioning incorrect.

So in the case of (b) it needs to carry out a face recognition on the "new" image and to add that into the database
.
In the case of (a) whilst the original metadata is embedded in the image, it isn't in the database for the new image. Yes it can be read back from the embedded metadata as described above, but if the image has been cropped or rotated, it won't necessarily be valid, so again rather than reading back what might no longer be valid, it is probably better to re-run the face recognition on that image.

Depending on the settings, face recognition on the new image mage be automatic and in that regard the following may help

Thanks I shall think about this. In my case original pictures are raw and the exported ones thes same but jpeg or Tiff. I jus would like identifoication kept even if face position (x,y) not.

To have face names and regions included in exported images you must first embed the proprietary AC meta data. The export routine can only include embedded meta data into the exported images. AFAIK the export function is unable to read meta data from the db and add it to exported files directly. To read all embedded meta data into the db you must catalogue the files, browsing the exported files is not sufficient. The handling of meta data in AC indeed is ... weird.
