(404 error) Category page. Language selected

Hello, Mr. Takayuki Miyoshi! Thank you for this good plugin!

I have some little problem) Could u help me, if it’s not so hard. I have woocommerce categories and activated plugin premmerce to delete ‘product-category’ from URL.

When language selected ‘en’:

Without Premmerce:
‘https://blackpepper.loc/en/product-category/catalog/tracksuits/’ this url works fine! Good!

With Premmerce:
‘https://blackpepper.loc/en/catalog/tracksuits/’ i have 404 error.

I have knowledges in PHP but not good with WordPress, if u can help me, I’d be happy)) I just want where i need change code to fix this problem)
I have idea to change:

if($category == 'product-category'){
str_replace('product-category', '', $category);
}

something like that…
