I recognize the importance of having your statements lodged accurately, linesvic.

We appreciate that you've already contacted our Phone Support team for help with unlodge some BAS statements. However, I still recommend contacting our QuickBooks Online Phone Support team again. Since they have the facility to undo a lodge BAS, they can verify why you're still seeing the original lodgement date and walk you through modifying it to get you back on track.

I'll add this article for your reference about fixing discrepancies with BAS amounts: What to do when BAS amounts look incorrect.

Please don't hesitate to reach out to us here in the Community space if you still have queries about unlodging BAS. We're here to help you in any way we can, linesvic.
