Unsynchroned Airtable record and GForm Response

at first this did not happen, until one month of use. suddenly it happened, not all of the recorded data from Gform entered the airtable, after I matched it was really lacking, 36 data should only enter 21, and when I repeat I delete and fill in Gform again, there should be 36 recorded data entered, but on the airtable only goes in 21, sometimes 30, 29, 34
