About I 140 ,eb2 priority date

Again my lawyer send mail like this,please advise

Hello
Please note as previously discussed with Attorney, the current I-140 downgrade/successor in interest cannot be Interfiled. The I-140 must continue to pend and be adjudicated by USCIS.
The EB-3 is current in the Final Action Chart this month and we are filing your daughter’s AOS based on the current EB-3 pending Downgrade/Successor in Interest - I-140.
