Flying economy - JNB - Windhoek.

The SAA ticket footnotes says:

The free checked baggage allowance per person in Economy class is 1 piece (max 50lbs/23kg & 62”/158cm ea.)

My ticket portion says:

Baggage (4): 2PC

In the notes, it says:

(4) Each passenger can check in a specific amount of baggage at no extra
cost as indicated above in the column baggage.

In manage my booking for myself and Mrs M each, it says 1 carry on bag and 2 checked bags.

Anyone ant idea which is the correct and what the maximum weights of the bags is?
