RoS 6.0rc12 SXT 2HnD scan list issues

When using the 5.24 RoS the scan list can be edited to “default,2414,2419…” I can not do this with the 6.0rc12. I have tried just entering the individual channels on each line but can not get the SXT-2HnD to connect on the 2414 or odd channels. Any help would be appreciated.
