Hi Shekhar Das,
Thank you for getting back to us. Please kindly do a plugin compatibility check by doing these steps to identify the error :
=> Deactivate all of your additional plugins except WooCommerce and Additional Variation Images Gallery Plugin.
=> See if the problem persists.
=> If the problem is resolved, you will understand which plugin might be the culprit of this error by activating your additional plugins one by one.
Looking forward to hearing from you soon.
Thank you

After installing the plugin, I get a double value to enter every time I add a new attribute to any product.
