Bug Report: Banners & Advertisement - Category Targeting Fails on Search Page

I'm writing to report a potential bug in the Banners & Advertisement Plugin v2.1.1 regarding its category targeting feature.
The Issue:
I have an advert that is configured in the admin panel to display only in one specific category (e.g., "Books - Magazines").
When I place the banner's hook in my search.php theme file, the advert is displayed correctly when I visit that specific category. However, the advert also incorrectly appears on the main, unfiltered search page (e.g., mysite.com/search), where all categories are shown.
Expected Behavior:
The advert should only be visible when a user is searching within or browsing the specific category assigned to it in the advert's settings. It should not appear on the general search page.

In ModelBA.php

find this code:
    if((osc_is_ad_page() || osc_is_search_page()) && (int)$cat_id > 0) {

replace with:
    if(osc_is_ad_page() || osc_is_search_page()) {


Work, thank you!
