Azure AI Search indexer shows correct total file count but the index has very less reference to the content of documents

Question

We have currently switched to ACS basic tier and each index has max storage 15gb. In my adls container I have an excel in a folder named content. Im using split skillset those chunk the file. After running g the indexer it ends quickly within 5-8secs and shows the correct file count that has been indexed and the documents or chunks in index should be around 4000 but it shows only 34. Total size of this index is 200kb and max size is 15gb. Earlier we had standard tier and this problem was not faced and I don't feel its due to the tier as available space is 15gb and the file size that I'm trying to index is of 980 kb.

Please helpe to resolve this issue quickly.
