NPM Network Topology unknown interfaces

Hello,

     We are moving to Solarwinds NPM from another vendor and installing trial version to test how it's going with our Juniper based network.

All thing are good but discovered something wrong in network mapping

Network Topology are declaring the connection between our switches through invalid interfaces and unknown ones as well as below (only the last line is correct and others are not) ..

Can anyone advise this behavior ?

also how Network topology get this statistics (CDP , LLDP, ARP ,,or what ?)

Note :SolarWinds-NPM-v11.0.1-Eval  is used
