Some strange behavior occur with views based on paragraphs: missing items, foreigner items; ghosts
Sorry for the translation ;)
1/ on D11.1.6 version, create a paragraph type + a node type that references this paragraph type
2/ create nodes with 1 or several paragraphs
3/ create a view based on paragraphs. Use 'fields' as display. The paragraph ID is added by default in fields.
4/ add a relation: entity referencing the paragraph
5/ in 'fields' add the field title that references the paragraph
6/ on some installs, foreign nodes without paragraphs ares listed + somes nodes referencing the paragraph are NOT listed / on some other installs, that works fine
7/ edit some nodes and delete paragraphs => on installs that worked fine before, the paragraph ID that had a paragraph some minutes before is still displayed = "ghost"
8/ edit again the nodes where you deleted the paragraphs before and add a paragraph => its paragraph ID is displayed ("ghost effect") but its title is NOT displayed
NB: views SQL show that LEFT or INNER JOIN are made on the VID and not on the NID. That should be a part of the problem.

NB: when doing a taxonomy based view instead of paragraph, on the worst install, the view works fine.
I have the feeling this issue is more from Paragraph than from Views.
