Currency field is empty while itemizing a transaction as expense ... "The total amount does not match with that of the uncategorized transaction"

While Categorizing the bank transaction as "Expense"... after choosing GST Treatment as "Out Of Scope" ... Whenever we select "Itemize"
It doesn't show anything in "Currency" ...... the Currency field is empty ... see the screenshots.....

Even if I ignore this .... and go on to save the form.... it shows the following error
"The total amount does not match with that of the uncategorized transaction"
See screenshots...
