Files are created with sparse attribute regardless of file alloc

While "fast allocate" method takes more time to allocate files (than with "sparse"), that files are still sparse, and are very fragmented after downloading. I completely removed torrent with files, set file allocation to full prewrite, then add it back - it takes much longer to allocate but files created still have sparse flag. Maybe it is an old bug, because I found this topic ( https://forum.tixati.com/support/3056  ) with similar problem.

I should have done it in first message.
Windows 10 version 1909, 64-bit
Tixati 2.64 64-bit
on NTFS
Also I tried rebooting and using another HDD volume but it didn’t help.

I compared Tixati allocation with µTorrent one.
Same torrent (~24 GB nearly all in one file), same NTFS volume (44% full), pre-allocation enabled in µTorrent, "fast allocate" in tixati.
Right after allocation: Tixati - 2957 fragments (sparse flag present), µTorrent - NO fragmentation (and no sparse flag). Fragment count observed via Defraggler.
