Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

You need to hook up the smoker PID for accurate calories data and HR.

I don't use GC. Are you sure the other five rides have power data in the files? Have you set up your user data with stuff like FTP? Is it possible the five empty ones haven't had their values set properly - maybe it can be configured per file? Try viewing them in WKO/TrainingPeaks or one of the other power apps - maybe Powertap's app? I can look at one in WKO and let you know if there's data in it? Or maybe Garmin Connect or Strava will show it?

If all 6 rides contain power data then check that your ftp is set correctly. GC allows you to set the start date for your ftp, so if you set your ftp today then historical rides will not show a TSS score as there will be no ftp data for the corresponding time period. you can set the "from" date in the user preferences window where you entered your ftp.

SwimScore, BikeScore and RunScore are all the same thing and are all Gc's own version of TSS. The only differences between them are that they use the appropriate estimate of threshold for that sport (ftp for BikeScore, threshold pace for run and swim). TriScore simply takes the Swim/Bike/RunScore for each workout so that all sports have a common metric. If a run has a RunScore of 50 then the TriScore is 50 and if a ride has a BikeScore of 110 then the TriScore is 110.

As I said above, TP automatically uses the best available metric to calculate TSS so it automatically estimates a runTSS and swimTSS for triathletes, and these numbers automatically filter through into TP's PMC chart. GC use the stricter calculation of TSS that requires power data. This means that TSS and the TSS based Coggan PMC chart in golden cheetah are only useful for pure cyclists using a powermeter. If you want to use data from multiple sports in gc then you need to use TriScore.

Last year I spent a few months manually entering all of TP's Swim/Bike/run metrics into GC and found that although TSS/TriScore occasionally differed slightly from one workout to another the differences were tiny and the Coggan PMC chart mapped perfectly with the TriScore PMC chart.
