Cash reporting different to when lodged

It has come to my attention that the my Cash GST report for BAS lodged to ATO at time of report was printed is different to when I prin that same report today?

I have gone through each quarter in FY21 and FY22 and there is a significant difference from the orignal printed report to a report on the 09.03.22 to see the difference 

I thought when you report CASH GST it is the money coming and money going out in that quarter?

It seems that all my prepayments that have been paid are not being picked up in that quarter, but adjusted when invoiced which is causing the difference.

This is concerning as FY21 is the first time this has happened and gives us false figures that gets reported to the ATO

Can anyone enlighten me on what has happened, has there been an upgraded which has reset my GST reporting.

I login to MYOB account right through an icon on my computer 

Today i logged into MYOB via the weblink by mistake and found that my figures were different again

Has anyone had any of these problems, it is very strange
