Need Technical Support on -  BNO055 - Difference between silk print A6 and A9

One of our productS has been using one of your components since last year.

Part Number : BNO055

Description: Intelligent 9-axis absolute orientation sensor.

However, we encountered some problems recently when we were using this BNO055 senero.

We were ordering/using as below before, it worked as expected.

Silk print:
701
A9
LRY 

However, the last batch we ordered didn't work as we expectation.After deeper investigation, we found the silk print differs from the ones we ordered before.

Silk print:
701
A6
LRY

We checked the datasheet, we found the 2nd line from your datasheet shows this is for your internal use purpose.

I contact you immediately and want to get your support on below points :

1>. What's the difference between A9 and A6? Are they compatible with each other?

2>.If A6 isn't compatible with A9, what's the best solution for us to correct the problem? (we found the A6 sensor doesn't work)

3>. Or maybe we ordered a wrong sensor or a fake sensor?

Looking forward to support and Thank you very much!
