LINTE, This seems to be sorting issue with respect to the app ids. It is just considering the first four digits of the application number for sorting in ascending/descing order, due to this it is not showing the application ids having more that 9999 based on the order and it is mixing up with the other apps considering only the first 4 digits. You can see the attached image RMApps.png which shows displaying the apps having id>9999 with other apps,
Please check and confirm whether is it happening same or not in your case by searching for the specific app id in the search box. Thanks.
