Phone calls of the second chip slot are muted [samsung j5lte]

Don't know how it's working in others phones but in mine (SM-J500M using j5lte/e/os) there is a bug on the second chip slot that makes all phone calls (recived and send) been muted. Thats an imporant issue because when I first used /e/ on my phone, I used this second chip slot as the main slot and couldnt make phone calls for a week until I tried to change the chip slot and figured out this bug. Maybe others phones are experiencing the same issue.
