Woocommerce Additional Variation Images not Deleting by WP Sheet Ediotr

Hey Folks,
We want to delete product variations easily just by finding them with SKUs for which we’re using WP Sheet Editor Premium. This plugin also has option to delete variation’s image which also gets deleted.

PROBLEM:
The problem is that we’re using “Woocommerce Additional Gallery Images” plugin by Woocommerce to add gallery images for each variation separately.
When we delete the variation, it gets deleted along with its main image. But gallery images are not getting deleted from media library.

Can anyone please help me in this?
