Google location service API: Only the first cell is taken into account in a list of several cell towers

Question

I'm developing a connected object with an LTE modem. I'm able to scan the surrounding cells. But every time I submit a list of several cells to the API, only the first one is taken into account.

A request with C1, C2, C3 returns the same result as C1 only A request with C3, C2, C1 returns the same result as C3 only

So a request with C1, C2, C3 does not give the same result as C3, C2, C1.

This problem is annoying because the other cells I have in the list are useless.

Note: I did the same test with wifi APs, and in this case it works correctly. I notice the problem only in the case of cell-id.

Thank you in advance for your help.
