Still getting ALL products results no matter what i search

So i had to change to another plugin due to this bug, just seach something, i get the results but also the rest of the products, i tried to go back after the update because i really like this plugin but seems that nothing changed, in the “Troubleshooting” part i get “Your site could not complete a loopback request” with the “Do you have a Basic Auth?” question, which answer is no, but i tried to add the “DGWT_WCAS_BA_USERNAME” and “DGWT_WCAS_BA_PASSWORD” stuff to the wp-config.php with no luck…

Any ideas? thanks!
