Add-on Price not working on Variation Products


I am using the YITH Product Add-ons and Extra options plugin for having options to select add-ons on a product.

I have configured it to increase the price of the selected product in percentages.

I am facing an issue with the add-on price update on variable products.

For example –
I have a product with variations ranging from 4749/- to 4999/-
I select the variation with a price of 4999/- and the YITH Add-on which should increase the price by 12% which is 599.88/-
But when I add it to the cart, the add-on price is 569.88/- which should be the price for the 4749/- variation.

Product page –
Checkout page –

This is causing an issue on the checkout as the price totals do not match on the product page and the checkout page.

Would greatly appreciate it if you could help me with this issue.
