Only some changes sync

[hynow]

Tasks created or marked complete in Thunderbird do not sync to Android. However, edits to descriptions and task deletions do sync, and edits to titles sync only sometimes. All changes made in Android sync to Thunderbird.

It occurs whether I am testing one action at a time, or attempting to sync multiple edits at once. As I perform different tests, changes from Android continue to sync to Thunderbird, but there are still tasks in Thunderbird not showing up in Android throughout all the syncing.

I am using Tasks.org (Android), DecSync CC, Syncthing (Android and Windows 10), Radicale-DecSync, Radicale, and Thunderbird (Windows 10). Is it possible to troubleshoot this? Thank you.
