Find the red circled area. You will see a reading for A --> B: 583.32 m there on the above report. It is where the damage is. If you are using the OTDR to find a physical damage of the cable, which you will only use the OTDR for, this is the only important reading you should care.
Following is a full report generated by an OTDR. Try to find the damage point by reading it. It's 56.86 m
