Hi Tejaskumar,
Thank you for sharing and elaborating on the issue you found.
At first glance, I think it is due to the large dataset you have in the table. Does your other document is also having many records in the table?
If so, it appears to be a bug in UI but functionality wise, it is working, correct? Because you mentioned you are able to get data in BP collection object.
Best regards,
