Some expenses are showing in the wrong quarter they have been entered correctly . Is there something in the background that needs amending?

entered correctly means what exactly?

the report basis is critical in this area, a report in cash basis will only show expenses actually paid in the report time period and not an expense listed on an unpaid bill.

accrual basis shows the expense as of the day it is listed on a bill, paid or unpaid, and of course any actual expense paid immediately

the same concept above is true for income
