Bing is spamming a single title tag result in all SERP snippets for an entire web domain

Hello, this is Davide Gherardi.
I work at the web office of the University of Bologna (Unibo) in Italy.
I have a problem with the snippet in Bing search results for the Unibo domain https://site.unibo.it/

The problem is the following: Bing is spamming in the snippet related to the domain site.unibo.it, the title tag "STUDI ETRUSCHI online" of a single page of a site: https://site.unibo.it/zich/it/corpora/studi-etruschi-online-1

Here are some examples:

How could I solve this problem?
Thanks!
