spurs on f3k

I am seeing a lot of spurs on the 20m band edge around 14.340 upwards. I have yet to check other bands, but found that although the spur reduction button removed some of them, there are still a lot of spikes within the last 10Khz of the band. Is this normal ? I also found that entering this 10k with the sr button off and then turning it on, creates more spurs, instead of removing them. A check on other bands reveals no spurs. The top image shows multiple qrm carriers from europe and also that away from the band end, no spurs. The 2nd image show me close to the band end and numerous spurs.
