Producer score is 0 in consumer score but producer score array have values 10,10

I got a simulcast consumer score object from mediasoup which is like this -

payload: Object
id: "8c68bd1b-8230-4be7-b86e-b1b026a993bb"
score: Object
producerScore: 0
producerScores: Array[2]
0: 10
1: 10
score: 10
type: "websocket/consumer-score"

Now here the produceScore is 0 but the producer score array have scores of 10.

What can be the issue here?
