amasty_xsearch_users_search table clean up is not working

Hi Amasty ,It is discovered that the size of the amasty_xsearch_users_search table is 1351 MB. We changed the Auto-Cleaning Period from 365 days to 30 days, and we have since verified that this change is not impacting the table's size.Because it affects the efficiency of the website, Adobe advises reducing the size of the table.Would you kindly check and verify cron job ?Regards
