AI from PDF keeps old thumbnail/preview
I often get someone's source documentation in PDF.
Yes, we should get source. No, it seems we can't get the soruce.
So - I open the PDF in Illustrator and save the useful chunks - graphics mostly - as separate files in .ai format, pdf-compatable.
For whatever reason, those docs usually will not preview correctly in Win Explorer or when browsing from ID to place as a graphic.
It seems there's some preview/thumbnail info from the original PDF that lingers in the AI file - even though it was a multi-page file, and I'm only using a piece of it from a page in the middle.
It seems that, because I opened the PDF and then saved it as AI, Illustrator doesn't clear out the old thumbnail info.

Update - still have the issue.
The system has Win 7 x64, Adobe CC / Illustrator 22.1
I7, 32GB Ram, SSD.
Can reliably open one page of PDF with IL, save as IL file, and preview fails.
If I create a new file in IL and copy content from the 'bad preview' file into the new one, that new file previews just fine.
