I see the problem. When I deleted the old cover img,
<meta name="cover" content="cover-f.jpg" />
was removed in content.opf.
After adding that back it becomes normal.
The thumbnail software choose is the first pic in alphabet order in Images floder.
I created a new clean file and using add cover function in Sigil to observe this.
I might consider rename my cover pic to "001-cover.jpg" or something to provide fallback.
