It appears that when the Bricksforge plugin is activated, information about whether tax is included or excluded in the price is always displayed in the WooCommerce cart and during checkout, even if the WooCommerce tax module is deactivated. This information may also appear somewhere in the user account, but I haven’t tested that. When I deactivate Bricksforge, the tax information disappears… I consulted this directly with Bricks Builder support, and they referred me to Bricksforge. Please help resolve this.
