T/B by Object Account subfile Cum amounts changing after Acct Bal by Period enquiry

Hi,

We are on A94 World with A9401.

We have been on A94 since Aug 2018.

We have come across a subfile display error.

When entering the T/B by Object Account if we use the option 2 against an account to view the Acct Bal by Period,

on the return if we page down it shows incorrect amounts on the Balance fields in the subfile.

The selection we use is for the end of the previous year using Cum for the head office company for one Object account, all Subledgers and all currencies for one Ledger Type.

If we press enter the subfile is rebuilt and the amounts are refreshed to what they should be.
