Web page asks proxy auth at every test case

Hello everyone, I am running some test cases under a proxy I made myself with squid.
The proxy uses username and password as authentication.
I put the proxy information in the preferences but at every Open Browser for each test case the web page can’t load and a pop-up asks me to enter username and password for the proxy connection.

I’m doing something wrong or there’s another way to prevent that pop-up to appear and load directly the web page?

I’ve checked again and seems like that katalon doesn’t pass the username parameter for the authentication.
I think that’s a bug
