You aren't, you're on 16QAM. Your modem is misreporting it.

If you have a look at the modulation types you'll see that for both advanced short and advanced long grants the modulation is 16QAM.

For whatever reason your modem is reporting the modulation of the maintenance and request bursts, which should be QPSK as relatively little bandwidth is needed for these but they must be robust.
