Hi @eneiss , the Loki configuration file https://grafana.com/docs/loki/latest/configure/
Is automatically generated from code comments and the template found in https://github.com/grafana/loki/blob/main/docs/templates/configuration.template.

In this case, the typo is in the file loki/pkg/validation/limits.go

Hi @JStickler, sorry for the confusion and thanks for the explanation!
I added my changes to limits.go and kept them in configuration.md since make doc from the repo root did not create any additional change.
Please let me know if that's not what should be done, and thanks for your help :)
