Thanks to @Saxo_Broko for reporting this issue. Apologies for the delayed follow-up.
Sync and scan-path handling have been substantially reworked across several releases:
v2024.3: Rewrote scan path configuration and duplicate detection; added sync reports so you can see exactly which directories were imported, skipped, or deferred.
v2026.1: Sync pipeline rearchitected — up to 6× faster on 8+ core CPUs, and the Filters settings now trigger automatic re-evaluation of already-imported files.
v2026.2: New Sync Activity page shows imports, directory status, and problem files in real time; a progress watchdog auto-restarts a wedged sync.
