Number or rows inconsistent while extracting GMX data.

While running "SELECT * FROM gmx_arbitrum.Vault_evt_IncreasePosition;" I am getting number of rows sometimes less than previous query output, It was 388628 rows on around 5th of January and currently it is showing 388560 rows and sometimes some other number, This is not possible as the transactions cannot decrease, i am also facing the same issue while running "SELECT * FROM gmx_arbitrum.Vault_evt_DecreasePosition; " kindly check.
