Inconsistent results when try to do a bulk capability check

Hello, i have a problem :D I've tried the node example in this repo https://github.com/rcs-business-messaging/rbm-api-examples. In particular, I did a bulk capibility check test, and I got some inconsistent results,

For example, assume we have the following numbers to check:

Capable
Not Capable
Not Capable

}

The call is correct in all three cases because a 200 is returned The question is why different results are returned based on the order of the three numbers I am passing?

Happened mostly with Serbian numbers, but also (sometimes) with Italian ones.

Any help is appreciated.

Thank you
