WPML multicurrency doesn't work with staff custom price & quantity

It only works if the product is set as DUPLICATE. As soon as you modify it with WPML Editor or WP Editor, the staff’s price & quantity is changed according to the multicurrency conversion:

Fixed Rate: 1 TRY = 0.125 USD

We conducted our experiment with the WPML editor. However, the system divides the amount for the second language at the same rate. When we set any amount limit for the personnel, we are faced with the table below.

The situation is as follows when only the WPML Editor is used.

Main Language : TR
Additional Cost: 80 TRY
Quantity: 8

Second Language: EN
Additional Cost: 10 USD
Quantity: 1

If the WP editor is used and the product is updated after the WPML editor, the situation changes from the WP Editor as follows.

Main Language : TR
Additional Cost: 80 TRY
Quantity: 8

Second Language: EN
Additional Cost: 10/8 = 1.25 USD
Quantity: 1/8 = 0.125
