How to remove delete-files of aws athena iceberg table

Aws athena iceberg table - i am using a merge into query, which is working as expected. But i noticed that the table referring to only 55 objects, whereas in s3 there around 250 objects. After exploring for some time, i understood that the other 200 files are delete-files. I am not storing any snapshots, so i dont require these s3 objects. Can someone help me understand how to delete those files?

JFYI… optimize and vacuum are clearing some unrequired data-files, but are not handling delete-files.
