Coverage disappears in nanopore segment of tutorial

[DKTMPELRN]

I'm going through the nanopolish part of the tutorial on WSL. It has mostly been running smoothly, generating the proper files etc. But the file output is different from the preview results in the tutorial. For example, the files example_nanopolish-freq-perCG.tsv and freq-perCG-combStrand should get a coverage of 7 according to the tutorial, but mine is consistently generating a coverage of 1 or 2:
