Why I cannot get GPS data correctly from pins 16, 17 on ESP32?

I’m trying to simply get the GPS data using ESP32-WROOM and Quectel L80 module. I want to send GPS data to my PC using Serial Monitor. So I have 2 UART configurations; one for GPS module and one for the debug message. Problem is when I connect GPS module to pins 16 and 17 I cannot get the GPS data correctly but I’m able to send debug messages to my PC. When I connect GPS module to pins 1 and 3 I’m able to get raw data correctly but this time not able to send debug messages to my PC.
