Problem with else if in Clion

#include <iostream>
using namespace std;
int main() {
    int A, B;
    while (true) {
        cout << "Unesite broj A: ";
        cin >> A;
        cout << "Unesite broj B: ";
        cin >> B;
        if ((A >= 10 || A <= 20) || (B >= 10 || B <= 20 ))
            break;
        else if ((A >= 50 || A <= 70 ) || (B >= 50 || B <= 70)) {
          break;
        }

    }

This is the code and everything after the second || in the first if condition is greyed out as a comment and I don't understand why. The whole else if condition is greyed out. I'm very new to c++ and I just switched from Dev c++ to Clion. Please help
