Batch Bug: Can't select columns in MP and XnConvert

[Stock]

This bug occurs in the Data Entry tab of the Batch Converter Tool. Have a look:

In this tab you feed in images to be batch-converted.
You may select between four different view modes.
As long as you have one of the 3 miniature modes selected (green circle), you may right-click the column titles and select the columns you like best.
As you can see, I've selected five columns and deactivated the rest.

Here comes the bug:

If you switch to detail mode (red circle), suddenly right-clicking on the column titles is impossible. Nothing happens.
Even worse, XnConvert has competely forgotten your prior column selection, instead it's always displaying all the columns.

Programs affected:
XnView MP 1.4.2
XnConvert 1.9.6

It's not a bug, columns can't be selected in 'batch convert'
