Vizlib pivot table in Custom report - column width not saved

Hello again

I can't manage to save the column width set in the analysis view:

After setting the width as desire, I go in edit mode and click on Save Default State

As you can see, all dimensions are stacked over each other even if it was not the case before going into edit mode.

When going back to analysis mode:

In the standard vilzib pivot table, column widths are correctly saved.

Would it be possible to do the same for custom reports in a future update ?

Thanks
