KBs short description not showing in Employee center search exact match

Hi Team,

I have a issue when KB articles are searched in Employee center with KB numbers the short descriptions are not showing for few articles in the Exact Match as showing in the attached screenshots. The issue is with the articles that are created using kb_template_faq , kb_template_how_to , kb_template_what_is templates.

For few articles the short description is showing as expected that are created with other templates.

Can anyone help me to understand what is the cause for this and how to fix the issue.

Thanks In Advance
