Kilosort3 returns units with 0 spikes after sorting

Hi,

Thanks again for your amazing work on Kilosort3 !

I use it with SpikeInterface wrapper and it returns some units with 0 spikes after sorting. I can't make sense of this. How can Kilosort3 create unit clusters without spikes?

See the problem's full description on SpikeInterface issue

@marius10p: Would you mind validating the explanation proposed by Samuel Garcia (see link)?

Thank you very much in advance,
Steeve
