Deleting/Creating Assets from contributor or via REST doesn't always trigger Lucien indexing or Dele

I have assets that are indexed as by name and parentname, name toknized false and stored true, parentname toknized is false and stored is false too.

On deleting one of these assets (created via REST or from contributor) via REST or from contributor, it doesn't always get deleted even if I get asset deleted message, it still shows in the contributor search, not in content tree or via Lucien search API, can't edit or redelete them ?

On Creating assets via REST, they don't all get indexed, they all are shown in the content tree but not in  the contributor search or retrieved by Lucien search API, they are indexed on editing them and start appearing in results ?
