you got many databases by the same name linked to your account which is confusing our system. Would suggest going into your online profile page here, glance down towards the Known Databases section of the page and removing ALL databases you currently linked to your profile: https://www.comicbase.com/mycb/profile.aspx
Next, make sure you're using the most up to date version of CB2023 (v23.2.2.2682). Download/install it from your online account here: https://www.comicbase.com/mycb/Registrations.aspx
Lastly, launch CB2023 and load in the database you wish to associate with CB mobile app. Go to the File Menu>Collection Statistics-this will give you the db's overall stats AND link it to your online profile/mobile app. Going forward, you should then be adding comics through the mobile app to that database.
