Contact Synchronization Issue on /e/OS

Has anyone experienced problems with contact synchronization on /e/OS? I’ve noticed that not all of my contacts are being synced properly from my Nextcloud account. Some contacts appear multiple times, while others don’t show up at all. Additionally, new contacts added on my phone don’t sync to Nextcloud. I’ve tried rechecking sync settings, removing and re-adding my Nextcloud account, and clearing the cache and data of relevant apps, but the issue persists. Any solutions or workarounds would be greatly appreciated.
