BE - AI Expert - Aggregation Issues

When the uploaded file is a PDF version of a csv/excel:

1) Fast Mode says - Chunk 8, Chunk 53. NOt a good user exp
2) Fast mode says - estimating

3) Pro Mode says - From available reference, maybe no tool calling
4) Pro Mode says - Estimated count, and asks me to go check manually


When the uploaded file is an Excel:

1) Fast mode gives wrong answers and only do reference check
2) Fast mode shows reference as chunks - wrong User experience

3)Pro Mode gives wrong answers & acceses reference

4) Pro mode gives right answer after human nudge

5) Pro mode actually mentions it is using Elastic search - tools should not be shown to the user
