Deleted items keep reappearing

Two deleted specific items keep reappearing everytime I relaunch the DTTG app. I tried following Utility Commands and other troubleshooting tips but they didn’t work:

-resync
-DTTGDebugCoreDataIntegrityCheck
-verify&repair database
-verify iCloud
-verify iCloud thoroughly

What should I do?

Provide more detail. What kind of documents, where are they located (imported, indexed?), anything in the logs?
