we had also faced similar issue on one of our site as well. The solution worked for us was that we needed to make an update directly to our master database.
For that we need to follow the three steps
1)connect to your master database and execute the following query which bring all the records where the "__Source Item" has updated as '19B597D3-2EDD-4AE2-AEFE-4A94C7F10E31' is the default field Id for "__Source Item"

SELECT TOP 100 [Id],[ItemId],[FieldId],[Value],[Created],[Updated]
FROM [SharedFields]
where Fieldid = '19B597D3-2EDD-4AE2-AEFE-4A94C7F10E31'
order by [Updated] desc

2)Then need to run the following command to delete that specific entry where there is some wrong value updated. By replacing the ItemId in the following query, the ItemId can be obtained through the query mention in the step 1)

DELETE FROM [SharedFields]
where FieldId='19B597D3-2EDD-4AE2-AEFE-4A94C7F10E31' and ItemId = 'yourItemId'

3) After deleting that entry from the database we need to restart the site.
