Magento2.4.5: Order total showing of a same product with diffrent size options in order detail page?

you can see from the image that the first row contains the sum of Subtotal, Tax Amount, Row Total This is not the Magento behaviour and I don’t understand how it happens
does anyone have any idea why the third row got created?

as you can see the first row contains the sum values of below these two rows, as magento default behaviour the first row shouldnt have created in the first place.
