CC1125: spurs close to carrier at 920MHz

Part Number: CC1125

I'm testing a product that uses the CC1125. The transmitter is hopping between 920MHz and 925MHz in 46 x 100kHz channels. On the bottom 10 channels there are spurs close to the carrier. At 920.25MHz there are spurs either side of the carrier at 250kHz deviation. I then tried this on the cc1125em cat1 evaluation board I have using RF studio V2.17.0(17/04/2020). Using one of the generic 868/915/920 profiles and changing the frequency to 920.25MHz I get exactly the same spurs as my hardware. So I'm thinking that this must be a register settings problem. Can anyone suggest anything?
