Hi @rachbeginner,
It seems like your theme is not BuddyPress- / rtMedia- friendly, which is causing these issues.
You might have to modify your template files ( https://rtmedia.io/docs/developers/themes/templating-system/ ) to fix the Media Page. Please refer to this docoment for examples - https://rtmedia.io/docs/developers/customize-media-gallery-template/
Let me know if this was useful.
Regards,
