You're matching the regex pattern of `/-/`, so it just matches every individual hyphen, regardless of where. You want to match the entire entry if it's only hyphens, or `/^-+$/`.
`^` – Beginning of line
`-+` – One or more hyphens
`$` – End of line
Putting that in gives
`awk 'BEGIN{FS=OFS="\t"}{gsub(/^-+$/,"",$72)}1' file.tsv`
which does what you want.
