Samplerate seems to be wrong for streams

I've been listening to an online radio station that has a 128k MP3 stream, and 32k and 64k AAC+ streams.  The 128k stream shows a sample rate of 44.1kHz, while the 32 and 64k streams show a sample rate of 22.0kHz.

However, in iTunes, and Foobar players on a computer, all streams show as 44.1kHz.  Is there something going on with the AAC+ streams in Xiia to reduce their sample rates, or are they simple being reported wrong on the screen?

The radio station I'm looking at is A Reason To Dance - Radio G!, but this seems to be true for any radio station streaming in AAC+ format that I've tested.
