Hi,
This might indicate a data inconsistency – updating from that very old release may caused it.
Can you please try the following:
– go to the index table options panel and save the settings without changing anything: https://i.imgur.com/dAGEjV9.png
– please do the same for all the search bars you have created before: https://i.imgur.com/0d15Aos.png
This should refresh any inconsistent information in the database and hopefully fix the issue.
