Bontact Breaks WooCommerce back end!

I have the problem described here:
https://www.ads-software.com/support/topic/product-data-tabs-not-working/

Basically, for some (wrong) reason, Bontact CSS loads even on Woocommerce backend pages, causing bootstrap.min.css to be loaded which conflicts with Woocommerce styling. The result is that the product tabs and other important UI elements are not showing!

You should make sure Bontact only loads CSS on pages it “owns”. And ideally prefix bootstrap classes with bontact_ to ensure it cannot conflict with WordPress styling either.
