This issue is because of the filesystem overlay for the new version after JSU. As the sysman-ui is not restarted, it will keep watching the /var/etc/config-apps.txt under the old release hence will not get any modification request.
The problem is still tracked by the JSU image team, customer can use below workaround to clear such issue.
The workaround could be like below.
Method 1: restart the whole router after installing the JSU image.
Method 2: Do cli command "restart sysman-ui" immediately after the JSU.
