Bug: Nothing named TIME:TS-LOAD has been defined

I have been trying to run a NetLogo simulation model but the time extension doesn't seem to work as intended. I am using the NetLogo 6.4 version on my mac OS Monterey.

The problem is that the commands time:ts-load gives the error "Nothing named TIME:TS-LOAD has been defined".

I have followed the instructions under Time Series Utilities from https://ccl.northwestern.edu/netlogo/docs/time.html. However, the link to the Time-Extension/time-series.nls shows 404 - page not found. Due to this I searched for the time-series.nls and found it under Time-Extension/src/time-series.nls instead. I downloaded it and added it to my directory where the .nlogo is located. I also added __includes [ "time.series.nls" ] in the top of the code. I also have the extensions [time table Csv rngs]. Unfortunately this did not remove the error.

I did not know where to reach out for help - so I though I could post it as an Issue here.

All help is very much appreciated!

Start with Time-Extension/src/time-series.nls and the Time Series Utilities documentation linked in the report. Reproduce the error in NetLogo 6.4 using the linked supermarket model and its time:ts-load call, then check whether the documented include path and filename match the repository file. The issue is resolved when the command is recognized without the reported error.
