Hi Sanjay,
If you put on the customer contact card that the sales currency is ZAR,
and if that numerical value is different than the previous rate (GBP), then by default it will cause some differences to show in SERP
The only way to avoid this if the new rate is the same as the old rate.
This should be the only cause of strange balances.
Can you please elaborate on exactly what balances you are seeing?
Thanks!
