We have noticed that after adding or mofify elements under SCP - admin - manage - Custom Lists, the search results with search criteria related to entries in the list are no longer available, older tickets are no longer found, specifically after the date the list was changed, earlier tickets with the same name in the list are no longer found, only newer ones from the date of the change.

It seems that all elements of the custom lists are given different ID numbers in the sql table, which affects the search results, which refer to objects in the list using search criteria.
We have long custom lists. Are there any limitations?
