user concern on Catalog view cannot find request for few catalog items in portal

[G Yaswanthreddy]

by selecting language preference as Chinese simplified and then search below catalog item title

Request Prohibited Software Exception

Service Not Listed

cannot find request catalog item. 

When a user searches for a term in English, but their preferred language is set to another. In this case, If a field lacks a translation in the user's session language, AI Search falls back to performing an exact match against the English-language field value.
The translations for sc_cat_item are stored in the following table:
System Localization Translated Text (sys_translated_text)

user is in japanese even the sys_translated_text for the japanese is not present for the catalog but catalog is visible in portal search same is not visible in the sc_cat_item list as well.
