Buddypress directory repair on a Sub-Site from a Wordpress Multisite

After a Buddypress single site is integrated in a Multisite Sub-Site, the Buddypress members are not shown in the Members Directory. What has been done so far: Until now, all files and the database of the single site have been properly integrated into the multisite. The single site now runs as part of the multisite at the following address: [login to view URL] What must be done: Since the single site is a Wordpress site with Buddypress and has now been integrated into the multisite, it happened that in the backend all members can be seen and the xProfile fields are filled out but the members are not shown in the members directory [login to view URL] Please fix this problem so that all users are shown in the members directory and Buddypress is working properly.
