Solr list of results displays different "Last modified date" than the page itself

How to reproduce:

• Create an app within minutes
• Add some fields in the app, but without the document content field
• create some entries
• later, edit those entries using the inline form sheet (default edit mode, not edit wiki or something)
• search for those entries using the solr search

Expected result:

• in the search results list, in the solr search, there is the information "last modified by ... on ..." . On the page of the document, under the title, there is the information "last modified by ... on ... ". The two dates are different for the entries of the application that were modified as described above

Actual result:

• the two dates should either be the same, or displayed using a different wording, to avoid confusion (it's difficult to understand why two pieces of information described in the same way are different)

Note: I did reindex the wiki, it's not a problem of outdated solr index.
