Importing Cub Adventures

We just signed up for our first year of TroopTrack and would like to get adventure progress for our pack migrated over. I’ve been able to export the advancements from Scoutbook but when attempting to import using the Scoutbook Advancement option, pretty much everything throws an error that starts with “Could not find troop achievement:”. Is there another way to get the achievements imported or am I in for a long slog of manual entry given where we are in the year?
