My synced Tracks are still in the list even though they don't match the conditions anymore

The sync in Tonkean is for continuously importing external items as Tracks into Tonkean. A common misconception is that once the Tracks no longer match the sync condition they would also be removed automatically. 

In reality, the sync operation would never remove items from the list, only add to it. The reason we do this, is because there could be valuable data on the Tonkean Track itself, for example, human input on the Track's progress. 

In order to accomplish an automatic removal of items when they are removed in the external system we recommend using our Bot Worker capabilities. You can look at an example in this guide.
