There is only one paragraph shown from the respondent. However, when viewing the plain-text version of the same ticket (https://ticket.wikimedia.org/otrs/index.pl?Action=AgentTicketPlain;TicketID=7933750;ArticleID=9407303) it shows multiple paragraphs that were omitted from the ticket view. The missing paragraphs also show up when you click reply.
There does not seem to be any (apparent) reason for this that we can see on our end.
