Web-ADS appears to be BROKEN.
If you use it to update anything for a matter with priority claims, it will edit the priority claim, and change the ordering of the elements.
This is true even if you do not change the priority data at all.
It will also insert an issue date for a Pending application.
This is a serious problem and means that despite its convenience we cannot use the Web-ADS for to update the ADS data.
Please fix this.
