Tvheadend

Hi I'm using the openelec 5RC1 build which includes tvheadend backend 3.9.2182~gbd20a53
When I check configuration>DVB Inputs>tv adapters tab the adapter name is shown but the adapter shows two interfaces, DVB-C & DVB-T. Pretty sure it should be only showing DVB-T2 not DVB-C. It's a pinnacle PC290e DVB-T2 USB adapter.
Nevertheless I try adding a network with the predefined muxes for my area(crystal palace) which inlcudes both DVB-T & T2 services. After they are added nothing gets scanned, Status tab shows no connections to the adapter. I've enabled both interfaces and ensured skip initial scan is not checked. Scan status for each mux remains in a pending state.
This was working fine on the previous stable build of openelec, 4.2.1
