Currency Calculation is not Working?

Hello. I want to ask something. I wonder why this is not the case in terms of currency calculation. There are currently currencies with different rates as foreign currency and TL.

The main unit is TRY. However, when there is income in the USD section, this amount does not appear in the monthly main income chart in the TL section.

Only TL payments and the total and earnings of income are shown. However, I had entered the exchange rate value.

Why is the total value not automatically calculated and shown there? In other words, it is not calculated and shown in the USD section in the dash board section. Although the current currency rate is included in the database, why is it not calculated and shown like that?
