I want to test cisco's flexible netflow with nbar support, but I have problem adding snmp device to Netflow Analyzer.

I enabled snmp debuging on CSR1000v (virtual cisco router) and I see "successfull snmp pooling":

but device is not added - it's stuck "INPROGRESS"

Any ideas what could be the problem? And how do I delete devices? In inventory I see 'edit' button, but it's just for editing names. Device is actually added if I understand correctly, I see interface speed, some data, I also see netflow datas, but without layer7 (nbar) support:
