Question SBE fix gives different result with shntool & flac front-end?

here's the shntool info on original files:
length expanded size cdr WAVE problems filename
8:51.48 93781908 -b- -- ---xx Track01.flac
14:12.74 150467836 -b- -- ---xx Track02.flac
11:51.70 125585712 -b- -- ---xx Track03.flac
17:21.18 183674548 -b- -- ---xx Track04.flac
52:17.61 553510004 B (totals for 4 files, 0.5096 overall compression ratio)

if i use shntool fix -o flac *.flac, i get:
Track01-fixed.flac:f1775ff933b949f297f0ff836d82bee2
Track02-fixed.flac:2a5f56b3c375b8d61f881f2d88ce808d
Track03-fixed.flac:2442d9a69bde6b6911eb1174547d83b7
Track04-fixed.flac:fce2288e1d15fd84d706d5b53defb01c

if i use flac > wav > flac (flac front-end with align on SBE), I get:
Track01.flac:f1775ff933b949f297f0ff836d82bee2
Track02.flac:2a5f56b3c375b8d61f881f2d88ce808d
Track03.flac:2442d9a69bde6b6911eb1174547d83b7
Track04.flac:a7e3d48aeefa4d2c5e5a4721063d2b5b

flac front-end log
options: --sector-align -P 4096 -b 4608 -m -l 8 -e -q 0 -r 0,6 -V
